Question

a current of 5mph a boat travel 210 miles downstream in the same amount of time it takes to travel 150 miles upstream. What is the speed of the boat still in water?

Raymond B. · Accepted Answer

distance = speed times time210 = (B+5)t150=(B-5)tt= 150/(B-5) = 210(B+5)cross multiply210B - 1050 = 150B + 75060B = 1800B = 30 mph in still water
