Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or kilometers per hour (km/h).

Front

What is the formula to calculate speed?

Back

The formula to calculate speed is: speed = distance / time.

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

Speed = 100 m / 5 s = 20 m/s.

Front

What units are commonly used to measure speed?

Back

Common units for speed include meters per second (m/s) and kilometers per hour (km/h).

Front

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

Back

To convert m/s to km/h, multiply by 3.6.

Front

If a runner completes a 400-meter lap in 50 seconds, what is their average speed?

Back

Average speed = 400 m / 50 s = 8 m/s.

Front

What is the average speed of a cyclist who travels 30 km in 1.5 hours?

Back

Average speed = 30 km / 1.5 h = 20 km/h.

Front

How do you find the distance traveled if you know speed and time?

Back

Distance = speed x time.

Front

If a train travels at a speed of 90 km/h for 2 hours, how far does it travel?

Back

Distance = 90 km/h x 2 h = 180 km.

Front

What is the average speed of a person who walks 1.5 km in 30 minutes?

Back

Average speed = 1.5 km / 0.5 h = 3 km/h.
