Question 42154: Glenn can row 7 mph in still water. If it takes him the same time to row 6 miles downstream as it takes to row 4 miles upstream, what is the rate of the crrent?
Answer by Paul(988) (Show Source): You can put this solution on YOUR website!
Let x be the rate of the current
EQUATION:
6(7-x)=4(7+x)
42-6x=28+4x
14=10x
x=1.4
Hence, the rate of the current is 1.4 mph
