Question

Martine completed a 66 kilometre cycling race at an average speed of 10.54 kilometres per hour. how long did he take to complete the race

Answer 1

It took them 6.262 hours to finish the race

Explanation:

Average speed = v = 10.54 km/h

Distance = d = 66 km

The formula for speed is,

Speed = distance/time

or,

v = d/t

for time, we get

t = d/v

so,

t = 66/10.54

t = 6.262 h
