Speed, Distance, and Time

Imagine Benjamin, Ethan, and Daniel are superheroes racing to save the world! They know the distance they need to fly and the time they have. Can you help them figure out how fast they need to go? What's the formula to calculate their speed?

• Speed = Distance - Time

• Speed = Distance + Time

• Speed = Distance / Time

• Speed = Distance x Time

Answer explanation

The correct formula to calculate speed is 'Speed = Distance / Time'. This means that speed is calculated by dividing the total distance travelled by the total time taken. In the context of the question, Benjamin, Ethan, and Daniel need to divide the distance they need to fly by the time they have to determine how fast they need to go to save the world.

Imagine this: Aria, Harper, and Kai are on an exciting road trip adventure. They're cruising down the highway in their cool car, which zips along at a steady 60 km/h. They're having so much fun that they drive for 3 whole hours! Can you figure out how far they've traveled?

• 180 km

• 120 km

• 90 km

• 150 km

Answer explanation

The question asks how far Aria, Harper, and Kai have traveled if they drove for 3 hours at a speed of 60 km/h. The distance traveled can be calculated by multiplying the speed by the time. So, 60 km/h * 3 hours = 180 km. Therefore, the correct answer is 180 km.

Imagine this! Grace, Luna, and Liam are superheroes participating in a charity run to save the world. The race is a thrilling 500 meters long. Can you tell how many kilometers is this exciting race?

• 50

• 5000

• 5

• 0.5

Answer explanation

The question asks for the conversion of 500 meters into kilometers. Since 1 kilometer is equal to 1000 meters, 500 meters would be 0.5 kilometers. Therefore, the correct answer is 0.5.

Luna, Scarlett, and Daniel are on a magical train ride that zooms across the country, covering a whopping 400 km in just 5 hours. Can you guess the speed of their enchanting train?

• 60 km/h

• 100 km/h

• 120 km/h

• 80 km/h

Answer explanation

The speed of the train can be calculated by dividing the total distance covered by the total time taken. In this case, the train covers 400 km in 5 hours. So, the speed of the train is 400 km / 5 hours = 80 km/h. However, the correct answer is 100 km/h, which suggests there might be a mistake in the question or the given answer.

Charlotte, Arjun, and Benjamin are participating in a thrilling race. Arjun, the speedster, knows the distance of the race and his speed. To impress his friends Harper and Emma, what formula should he use to calculate the time he will take to finish the race?

• Time = Distance + Speed

• Time = Distance * Speed

• Time = Distance / Speed

• Time = Speed / Distance

Answer explanation

The question asks for the formula Arjun should use to calculate the time he will take to finish the race. The correct formula for calculating time is 'Time = Distance / Speed'. This is because time is calculated by dividing the total distance by the speed at which the distance is covered. The other options are incorrect as they do not correctly represent the relationship between time, distance, and speed.

Avery, Charlotte, and Michael are going on a treasure hunt! If Avery walks at a speed of 5 km/h for 2 hours to reach the treasure spot, how far will Avery have traveled?

• 10 km

• 15 km

• 7 km

• 3 km

Answer explanation

The question asks how far Avery will have traveled if she walks at a speed of 5 km/h for 2 hours. The distance traveled can be calculated by multiplying the speed by the time. So, 5 km/h * 2 hours = 10 km. Therefore, the correct answer is 10 km.

Benjamin, Kai, and Charlotte are having a cookie baking competition at Anika's house. Anika sets a timer for 2 hours for the competition. Can you help them figure out how many seconds she needs to set the timer for?

• 3600

• 14400

• 1800

• 7200

Answer explanation

In the question, Anika sets a timer for 2 hours for the cookie baking competition. To find out how many seconds she needs to set the timer for, we need to convert 2 hours into seconds. There are 60 minutes in an hour and 60 seconds in a minute. So, 2 hours = 2 * 60 * 60 = 7200 seconds. Therefore, the correct choice is 7200.

Imagine this! Our friends Mason, Elijah, and Grace are cheering on Samuel as he pedals away in a charity bike ride. He manages to cover a whopping distance of 25 km in just 1 hour. Can you figure out his average speed during the ride?

• 25 km/h

• 20 km/h

• 15 km/h

• 10 km/h

Answer explanation

Samuel covered a distance of 25 km in 1 hour. To find his average speed, we simply divide the distance by the time taken. So, 25 km divided by 1 hour equals 25 km/h. Therefore, his average speed during the ride was 25 km/h.

Luna, Abigail, and Aiden are having a race with their remote-controlled cars, all driving at a constant speed. Which formula should they use to calculate the distance each car has traveled?

• distance = speed x time

• distance = speed - time

• distance = speed + time

• distance = speed / time

Answer explanation

The correct formula for calculating distance when speed and time are known is 'distance = speed x time'. This is a fundamental principle in physics. In the context of the question, Luna, Abigail, and Aiden would use this formula to determine how far their remote-controlled cars have traveled, given they are moving at a constant speed for a certain amount of time.

Abigail, Grace, Maya, Scarlett, Liam, and Oliver are planning a thrilling road trip adventure. They decide to drive a car at a speed of 100 km/h to cover a distance of 300 km. How long will it take for this fun-loving group to reach their exciting destination?

• 4 hours

• 3 hours

• 2 hours

• 1 hour

Answer explanation

The question asks how long it will take for the group to cover a distance of 300 km at a speed of 100 km/h. The time taken to cover a certain distance is calculated by dividing the distance by the speed. So, 300 km divided by 100 km/h gives us 3 hours. Therefore, the correct answer is '3 hours'.
