Problema Solution

a boat goes upstream in 3 hours

it comes back down in 2 hours

What is the speed of the boat

Answer provided by our tutors

 

Let the speed of boat in still water be x and the speed of river be v

So upstream d=(x-v)3

downstream d= (x+v)2

Equsting we get x=5v

The speed of  boat is 5 times the velocity of river
