Question
Boat ‘A’ can cover 150 km in still water in 15
hours. In still water, if the ratio of the speed of boat ‘A’ to that of ‘B’ is 5:1 and the speed of stream is 3 km/hr then find the time taken by boat ‘B’ to cover the 60 km in downstream.Solution
Speed of boat ‘A’ in still water = 150/15 = 10 km/hr Speed of boat ‘B’ in still water = 10 × (1/5) = 2 km/hr Downstream speed of boat ‘B’ = 2 + 3 = 5 km/hr Time taken by boat ‘B’ to cover 60 km in downstream = 60/5 = 12 hours
