Solve the problem. A boat can go 33 mph in still water. It takes as long to go 300 miles upstream as it does to go downstream 360 miles. How fast is the current?

Downstream velocity is vb+vs

Upstream velocity is Vb-Vs

You are given Vb.

upstream: 300=(vb-vs)T

downstream:360=(vb+Vs)T

add the equations...

660=2vbT solve for time. Then, go back to either equation and solve for vstream.
