A tugboat goes 180 miles upstream in 15 hours. The return trip downstream takes 10 hours. Find the speed of the tugboat wihtout a current and the speed of the current.
--------------------------
Upstream DATA:
distance = 180 miles ; time = 15 hrs ; rate = 180/15 = 12 mph
-----
Downstream DATA:
distance = 180 miles ; time = 10 hrs ; rate = 180/10 = 18 mph
------
Equation:
Upstream: b - c = 12 mph
Downstrm: b + c = 18 mph
