Randy, Using his motorboat, took 5 hours to make a downstream trip in a river with a current 8 kph. The return trip upstream took 9 hours. What is the total distance traveled by Randy's boat?
**
let x=speed of motorboat in still water
x+8=speed of motorboat downstream
x-8=speed of motorboat upstream
distance=travel time*speed
..
5(x+8)=9(x-8)
5x+40=9x-72
4x=112
x=28
distance traveled by Randy's boat=5(x+8)=5*36=180 km
