Question
A motorboat covers 96 km downstream in 4 hours. Coming back
upstream over the same distance, it takes 8 hours longer than the downstream time. Find the speed of the boat in still water.Solution
ATQ,
Downstream speed = 96 / 4 = 24
Upstream speed = 96 / 12 = 8
V + U = 24
V – U = 8
By solving, we get V = (24 + 8) / 2 = 16 km/hr
