a boat travels 48 miles downstream and back. the trip downstream took 3 hours. the trip back took 8 hours. find the speed of the boat in still water and the speed of the current.
-----------
d = r*t
r = d/t
----
Find the 2 speeds, u/stream and d/stream.
---
The boat's speed is the average of the 2 speeds.
---
Can you figure out the current?
