Question
The speed of a boat in still water is 10 km/hr more than
that of the current. The time taken by the boat to cover 575 km downstream is 11.5 hours. Find the total time taken by boat to travel 650 km downstream and 30 km upstream.Solution
Therefore, downstream speed of the boat = 575/11.5 = 50 km/hr And, upstream speed of the boat = 10 km/hr Required time taken = (650/50) + (30/10) = 13 + 3 = 16 hours
