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
