Question
A boat can cover 70 km in still water and 72 km in
downstream in 4 hours and 3 hours respectively. Find the time taken by the boat to cover 66 km upstream and 48 km downstream.Solution
Speed of the boat in still water = 70/4 = 17.5 km/h Downstream speed of the boat = 72/3 = 24 km/h Speed of the stream = 24 – 17.5 = 6.5 km/h Upstream speed of the boat = 17.5 – 6.5 = 11 km/h Time taken to cover 66 km upstream and 48 km downstream = 66/11 + 48/24 = 6 + 2 = 8 hours
