Flying against the wind, a jet travels 6930 miles in 9 hours. Flying with the wind, the same jet travels 6060 miles in 6 hours. What is the rate of the jet in still air and what is the rate of the wind?

6930 / 9 = 770 m/hr

6060/6 = 1010 m/hr

 

jet speed in still air is the average  = 890 m/hr

   wind speed is diff between this speed and one of the above speeds =  120 m/hr
