Question
Boat ‘A’ covers 150 km in downstream in 15 hours. If
the speed of stream is 2 km/hr then find the time taken by boat ‘A’ to cover 108 km in upstream.Solution
Downstream speed of boat ‘A’ = 150/15 = 10 km/hr Speed of boat ‘A’ in still water = 10 – 2 = 8 km/hr Upstream speed of boat ‘A’ = 8 – 2 = 6 km/hr Time taken by boat ‘A’ to cover 108 km in upstream = 108/6 = 18 hours
