Tom can row a boat in still water at a rate of 5miles per hour. If he is rowing upstream and the stream is moving at a rate of 4 miles per hour, how long will it take tom to row 3 miles?

Answer 1

It depends on the energy of river which is being affected by wind speed in this case.

distance = rate*time
3 = (5-4)*t
3 = t

It will take 3 hours to row 3 miles against the current
