Flying against the wind, a jet travels 3040 miles in 4 hours. Flying with the wind, the same jet travels 8260 miles in 7 hours. What is the rate of the jet in still air, and what is the rate of the wind?
Velocity of jet in still air is
Jet's velocity against wind is
Let the velocity of jet in still air be
As such its velocity against wind is
Adding the two
Hence velocity of jet in still air is
