Question

A man takes 2.2 times as long to row a distance upstream as to row the same distance downstream. If he can row 55 km downstream in 2 hours 30 minutes, what is the speed of the boat in still water?

Answer 1

Answer:

Explanation:

Speed up stream=2.2*150=330min

Speed=distance/time =330/55=6km/hr

Speed downstream=150/55=2.7km/hr.

Speed of stream =6-2.7=3.3km/hr.
