Question

Solve the given problems applying the Polya’s 4 steps in showing the solutions.




1. a plane traveled 600 miles to Zamboanga and back. The trip there was with the wind. It took 2 hours. The trip back was against the wind. The trip back was 6 hours. Find the speed of the plane in still air and speed of the wind.​

Answer 1

Answer:

Let the speed of the airplane = x

Let the speed of the wind = y

The airplane travels 600 miles against the wind in 4 hours

600 = 4*(x-y) ...(1)

It makes the return trip with the same wind in 2 hours

600 = 2*(x+y) ...(2)

(2)*2=>

1200=4*(x+y) ...(3)

(2)-(3)=>

-600 = - 8y

8y=600

y=600/8

y=75 m/h

So, the speed of the wind = y = 75mph
