Speed, Distance, and Time Challenge

Front

A cheetah running at a speed of 30 m/s will cover in one minute

Back

1800 m

Answer explanation

To find the distance covered in one minute, multiply the speed (30 m/s) by the time (60 seconds). Thus, 30 m/s * 60 s = 1800 m. Therefore, the correct answer is 1800 m.

Front

What is needed to determine the speed of an object?

Back

distance and time

Answer explanation

To determine the speed of an object, you need to know the distance it travels and the time it takes. Speed is calculated as distance divided by time, making 'distance and time' the correct choice.

Front

What is this the unit for? Distance, Time, Speed

Back

Speed

Answer explanation

The correct answer is 'Speed' because speed is defined as the distance traveled per unit of time. It is a measure of how fast something is moving, making it distinct from distance or time alone.

Front

A car travels 150 miles in 3 hours. What is the average speed of the car in miles per hour?

Back

50 mph

Answer explanation

To find the average speed, divide the total distance by the total time. Here, 150 miles ÷ 3 hours = 50 mph. Therefore, the average speed of the car is 50 mph.

Front

If a cyclist travels at a speed of 12 miles per hour, how far will they travel in 2.5 hours?

Back

30 miles

Answer explanation

To find the distance traveled, multiply speed by time: 12 miles/hour * 2.5 hours = 30 miles. Therefore, the cyclist will travel 30 miles.

Front

Convert a speed of 90 feet per second to metres per second. (1 metre = 3.281 feet)

Back

27.4 m/s

Answer explanation

To convert 90 feet per second to metres per second, divide by 3.281. Thus, 90 ÷ 3.281 ≈ 27.4 m/s. Therefore, the correct answer is 27.4 m/s.

Front

A train travels 240 miles in 4 hours. What is the speed of the train in miles per hour?

Back

60 mph

Answer explanation

To find the speed, divide the distance by the time: 240 miles ÷ 4 hours = 60 mph. Therefore, the speed of the train is 60 mph.

Front

If a runner maintains a speed of 8 miles per hour, how long will it take them to run 20 miles?

Back

2.5 hours

Answer explanation

To find the time taken, divide the distance by speed: 20 miles ÷ 8 miles/hour = 2.5 hours. Therefore, the correct answer is 2.5 hours.

Front

Convert a speed of 100 miles per hour to feet per second. (1 mile = 5280 feet)

Back

148.0 ft/s

Answer explanation

To convert 100 miles per hour to feet per second, use the conversion: 100 miles/hour × 5280 feet/mile ÷ 3600 seconds/hour = 148.0 ft/s. Thus, the correct answer is 148.0 ft/s.

Front

A person walks 300 metres in 5 minutes. What is their speed in metres per second?

Back

1.0 m/s

Answer explanation

To find speed, divide distance by time. Here, speed = 300 metres / (5 minutes × 60 seconds/minute) = 300 / 300 = 1.0 m/s. Thus, the correct answer is 1.0 m/s.
