Back

Total distance = average speed x total time

Front

If a person walks at an average speed of 4 km/h for 1.5 hours, how far do they walk?

Back

Distance = 4 km/h x 1.5 hours = 6 km

Front

What is the average speed of a vehicle that travels 100 miles in 2 hours and then 50 miles in 1 hour?

Back

Total distance = 100 miles + 50 miles = 150 miles; Total time = 2 hours + 1 hour = 3 hours; Average speed = 150 miles / 3 hours = 50 miles/hour

Front

If a runner has an average speed of 8 m/s, how long will it take them to run 400 meters?

Back

Time = distance / speed = 400 m / 8 m/s = 50 seconds
