A motorboat travels 225km in 5 hours going upstream. It travels 305km going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current?
-------------------
Find the 2 speeds, up and down stream.
the boat's speed is the average of the 2.
----------
B = (U + D)/2
===================
The current is the difference between the boat's speed and either the up or down stream speed.
