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 4:3 and the speed of stream is 3 km/hr then find the time taken by boat ‘B’ to cover the 234 km in downstream.Solution
Speed of boat ‘A’ in still water = 160/8 = 20 km/hr Speed of boat ‘B’ in still water = 20 × (3/4) = 15 km/hr Downstream speed of boat ‘B’ = 15 + 3 = 18 km/hr Time taken by boat ‘B’ to cover 234 km in downstream = 234/18 = 13 hours
