Question

A bicycle completed the first 500.0 m of a ride in 99.8 s. What was the bicycle’s average speed in kilometers per hour?

Answer 1

500 meters * [ 1 km / 1000 m ] = 1/2 km = 0.5 km

99.8 s [1 hour/ 3600 sec ]= 0.02772222 hour

Rate = distance / time

Rate = 0.5 km / 0.0277722222 ... = 18.036072 km/hour
