Question 1199505: A riverboat travelling with the current can go 60 km in 3 hours, on the return trip against the current it took 4 hours to travel the 60 km. Which of the following would represent a linear system that could be used to determine the speed of the riverboat and the current where x is the speed of the riverboat and y is the speed of the current?

No "following" answer choices are shown....

The downstream speed is x+y; the upstream speed is x-y. So one possible system of equations (distance = rate * time) is

3(x+y)=60
4(x-y)=60
