Question
Boat ‘A’ can cover 160 km in still water in 8 hours.
In still water, if the ratio of the speed of boat ‘A’ to that of ‘B’ is 2:3 and the speed of stream is 5 km/hr then find the time taken by boat ‘B’ to cover the 350 km in downstream.Solution
Speed of boat ‘A’ in still water = 160/8 = 20 km/hr Speed of boat ‘B’ in still water = 20 × (3/2) = 30 km/hr Downstream speed of boat ‘B’ = 30 + 5 = 35 km/hr Time taken by boat ‘B’ to cover 350 km in downstream = 350/35 = 10 hours
