A plane traveled 1440 miles to México City and back.

Question

A plane traveled 1440 miles to Mexico City and back. The trip there was the wind. It took 12 hours. The trip back was into the wind. The trip back took 24 hours. What is the speed of the plane in still air? What is the speed of the wind? (Write it in x and y)

Answer 1

d = r * t

1440 = 12(p + w)

1440 = 24(p - w)

1440 = 12p + 12w

1440 = 24p - 24w

Can you solve for p or w and answer?
