Speed, Distance, and Time Concepts

The video tutorial introduces the concepts of speed, distance, and time, explaining how speed is the distance traveled over a certain time. It covers the units of measurement for speed, distance, and time, and provides formulae for converting speed between kilometers per hour and meters per second. An example problem is solved to demonstrate these calculations. The video concludes with a recap of the formulae and encourages viewers to practice solving problems on their own.

What is the unit of speed when a car travels 90 km in one hour?

• 90 m/s

• 90 km/s

• 90 km/h

• 90 m/min

Which of the following is NOT a unit of distance?

• Kilometers

• Hours

• Meters

• Centimeters

How do you convert speed from km/h to m/s?

• Multiply by 1000

• Multiply by 60

• Multiply by 5/18

• Multiply by 18/5

If a speed is given in m/s, how can it be converted to km/h?

• Multiply by 60

• Multiply by 18/5

• Multiply by 1000

• Multiply by 5/18

A truck covers 210 km in 3 hours. What is its speed in km/h?

• 90 km/h

• 60 km/h

• 70 km/h

• 80 km/h

Using the conversion formula, what is the speed of the truck in m/s if it travels at 70 km/h?

• 21 m/s

• 20 m/s

• 22 m/s

• 19 m/s

What is the formula to calculate speed?

• Speed = Distance / Time

• Speed = Time x Distance

• Speed = Time / Distance

• Speed = Distance x Time

How can you calculate distance if speed and time are known?

• Distance = Speed + Time

• Distance = Time / Speed

• Distance = Speed x Time

• Distance = Speed / Time

What is the formula to find time if distance and speed are given?

• Time = Speed / Distance

• Time = Speed x Distance

• Time = Distance x Speed

• Time = Distance / Speed

Which of the following is a unit of time?

• Meters

• Seconds

• Centimeters

• Kilometers
