Let = time in hrs to travel downstream
= time in hrs to travel upstream
Let = one way distance
Let = the speed of the boat in still water
Let = the speed of the current
------------------------------------------
Equation for going upstream:
(1)
Equation for going downstream:
(2)

For the same distance, the ratio of times is 1.5:1, or 3:2; that means the ratio of speeds is 2:3.
If b is the boat's speed and c is the speed of the current, then the upstream speed is b-c and the downstream speed is b+c. So
The ratio of the boat's speed to the speed of the current is 5:1.
