Question 807021: A man rows a boat 420 feet upstream against a constant current in 12 minutes. He then rows 330 feet downstream (with the same current) in 6 minutes. Find the speed of the current and the equivalent rate at which he can row in still water
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
Distance equals rate times time so distance divided by time is rate. Total speed downstream is 
and total speed upstream is 
where 
is speed in still water and 
is the speed of the current.
Both values in feet per minute. Solve the 2X2 system for and
