Question
The downstream speed of a boat is 6 km/hr more than its
upstream speed and the ratio of the speed of the boat in still water to the speed of the stream is 8:3. Find the total time taken by boat to travel 33 km downstream and 25 km upstream?Solution
Let the speed of boat in still water be x km/hr and that of stream be y km/hr. ATQ, ⇒ (x + y) – (x – y) = 6 ⇒ y = 3 km/hr ⇒ x = 3 × 8/3 = 8 km/hr Required time = [33/(8+3)] + [25/(8−3)] = 8 hr
