Question
The speed of the stream is 12
km/h, and the speed of the boat in still water is 50% greater than the speed of the stream. Calculate the total time required for the boat to cover 18 km upstream and 45 km downstream.Solution
ATQ,
Speed of boat in still water = 1.5 × 12 = 18 km/h Upstream speed = 18 – 12 = 6 km/h Downstream speed = 18 + 12 = 30 km/hr Desired time = 18/6 + 45/30 = 3 + 1.5 = 4.5 hours
