Question

Flying against the wind a jet travels 5040 miles in 8 hours flying with the wind the same jet travels 6780 miles in 6 hours. What is the rate of the jet in still air and what is the rate of the wind?

Answer 1

(Wind speed: 81,000) and (Rate of the jet in still air: 11,820)

Explanation:

We know that 5040 times 8 is 40320.

And 6780 times 6 is 40680.

Then, add them together and the rate of the wind is 81,000.

The rate of the jet, add them (6780 plus 5040) and you'' get 11,580.
