Question

14] 12. At the speed of 18 km/h, a cyclist covers a distance in 180 minutes. At what speed can he cover the same distance in 4 hours?
​

Answer 1

Answer & Explanation:

First calculate the distance

distance = speed x time

distance = 18 x (180/60) [convert minutes to hours]

distance = 54 km

finally calculate the speed

speed = distance / time taken

speed =  54 / 4

speed = 13.5 km/h
