Here's a solution to a similar problem.
=======================
A motor boat can travel 45 kilometers downstream in 2 hours and 30 minutes and 39 kilometers upstream in 3 hours and 15 minutes. what is the speed of the boat in still water? what is the speed of the current?
===============
Find the 2 "groundspeeds."
The boat's speed wrt the water is the average of the 2.
The current is the difference between the boat's speed and groundspeed.
