Question 847758: A boat traveled downstream a distance of 36 mi and then came right back. If the speed of the current was 6 mph and the total trip took 4 hours and 30 minutes, find the average speed of the boat relative to the water.
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
The current adds to the speed going
downstream, and subtracts from the speed
going upstream, so the effect of the
current cancels to zero
-----------------------
The total distance is mi
Let = the average speed of the
boat relative to the water
-----------------------
mi/hr
