Motorboat travels 9 miles downstream (with the current) in 30 minutes. The return trip upstream (against tt
takes 90 minutes.
Which system of equations
can be used to find x, the speed of the boat in miles per hour, and y, the speed
current in miles per hour? Recall the formula d = rt.
β’ 9 0.5(x - y)
9 = 1.5(x + y)
- 1.5(x -y)
9 = 0.5(x + y)
0.5 = 9(x - y)
1.5 = 9(x + y)
1.5 = 9(x -y)
0.5 = 9(x + y)
