Question
The speed of a boat in still water is 6 km/hr more than
that of the current. The time taken by the boat to cover 875 km downstream is 17.5 hours. Find the total time taken by boat to travel 650 km downstream and 45 km upstream.Solution
Therefore, downstream speed of the boat = 875/17.5 = 50 km/hr And, upstream speed of the boat = 6 km/hr Required time taken = (650/50) + (45/6) = 13 + 7.5 = 20.5 hours
