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?
DownstreamUpstream Time-5:11=>2.2=22/10=11/5 Speed- 11:5 Let the Downstream Speed=11x and upstream speed =5x Now ATQ- 11x =55/2.5 X=2 Speed of boat in still water =(11x+5x)/2 =16x/2=8x =8×2=16km/h
