Question 435128: If it takes 3 hrs to travel 15 miles downstream and 5 hr to travel upstream, how fast is the current if the speed of the boat remains constant? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! 15/3=5 mph
15/5=3 mph
5+3/2=4 mph equals speed of the boat
5-4=1
4-3=1
The speed of the current is 1 mph..
