Question

3. When a boat traveled downstream from Town A to Town B, the trip took 3 h. When the same boat traveled upstream from Town B to Town A, the trip took 3.6 h. For each trip, the speed of the boat and the water current were unchanged. Let x represent the speed of the boat and let y represent the speed of the water.

(a) Write an expression for the distance traveled downstream using 3 h for the time. Then write an expression for the distance traveled upstream using 3.6 h for the time.


(b) Set the expressions in Part (a) equal to each other. Then solve the equation for y. Show your work.

Answer 1

(c) What percent of the boat’s speed is the water current?

Answer 2

there's the rest.
