Question 394298: Please show me the solution of this problem: "In 6 hours, two men can row 16 miles downstream on a river and back. Their rate upstream is twice the rate of the current. Find the rate of the current." Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! In 6 hours, two men can row 16 miles downstream on a river and back.
Their rate upstream is twice the rate of the current.
Find the rate of the current."
:
let x = rate of the current
then
2x = the rate going upstream
and
3x = rate in still water;
and
4x = rate going downstream
:
write a time equation; time = dist/speed
:
Upstream time + downstream time = 6 hrs + = 6
Multiply by 4x, results
2(16) + 16 = 6(4x)
32 + 16 = 24x
48 = 24x
x =
x = 2 mph is the current
