Question
Speed of a motorboat in still water is 50 km per hour if the motorboat travels 80 km along the stream in 1 hour 20 minutes, then the time taken by it to cover the same distance against the stream will be.
Upstream speed=B-S=50-10=40km/h Time =Distance/Upstream speed =80/40=2hours.More Boats and streams Questions
