Question 116182: Solve the problem. A boat can go 33 mph in still water. It takes as long to go 300 miles upstream as it does to go downstream 360 miles. How fast is the current?
Answer by checkley71(8403) (Show Source): You can put this solution on YOUR website!
300/(33-C)=360/(33+C) CROSS MULTIPLY.
360(33-C)=300(33+C)
11880-360C=9900+300C
-360C-300C=9900-11880
-660C=-1980
C=-1980/-660
C=3 MPH IS THE SPEED OF THE CURRENT.
PROOF
300/(33-3)=360/(33+3)
300/30=360/36
10=10
