Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is usually expressed in units such as km/h or m/s.

Front

How do you calculate average speed?

Back

Average speed = Total Distance / Total Time.

Front

If a horse travels 3 km in 10 minutes, what is its average speed in km/min?

Back

Average speed = 3 km / (10 min) = 0.3 km/min.

Front

Convert 0.3 km/min to km/h.

Back

0.3 km/min = 0.3 * 60 = 18 km/h.

Front

What is the average speed of a toy car that travels 2 meters in 1.5 seconds?

Back

Average speed = 2 m / 1.5 s = 1.33 m/s.

Front

If a student walks 2 km in 30 minutes, what is their average speed in km/h?

Back

Average speed = 2 km / (30 min) = 4 km/h.

Front

A bus travels 20 km in 30 minutes. What is its average speed?

Back

Average speed = 20 km / (0.5 h) = 40 km/h.

Front

What is the average speed of a toy car that rolls across a 2-meter table in 11.1 seconds?

Back

Average speed = 2 m / 11.1 s = 0.18 m/s.

Front

How do you convert km/min to m/s?

Back

To convert km/min to m/s, multiply by 1000 (to convert km to m) and divide by 60 (to convert minutes to seconds).

Front

What is the formula for converting speed from km/h to m/s?

Back

To convert km/h to m/s, divide the speed by 3.6.
