Question
A cyclist moves from location ‘L’ to location ‘M’,
covering (1/2) of the total distance in 4 hours and the rest in 3 hours. If he comes back to ‘L’ from ‘M’ in 5 hours, calculate his average speed for the entire journey, given that the distance between ‘L’ and ‘M’ is 35 km.Solution
ATQ,
Average speed = total distance covered ÷ total time taken
Total time taken = 4 + 3 + 5 = 12 hours
Total distance covered = 35 × 2 = 70 km.
Required average speed = 70/12 = 5.83 km/h
