Don Williams uses his small motorboat to go 4 miles upstream to his favorite fishing spot. Against the current, the trip takes 1/3 hour. With the current the trip takes 1/6 hour.
---------------------
With the current DATA:
dist = 4 mi ; time = 1/6 hr ; rate = 4/(1/6) = 24 mph
-----------------
Against the current DATA:
dist = 4 mi ; time = 1/3 hr ; rate = 4/(1/3) = 12 mph
--------------
Find the speed of the current:
b + c = 24 mph
b - c = 12 mph
-----------------
2c = 12 mph
Current = 6 mph
