A jet travels 3950 miles from Chicago to London and then returns. The total flying time for the round trip is 16.5 hours. The return trip takes longer due to the wind. If the jet's average speed with no wind is 485 mi/hr, what is the average speed of the wind during the round trip flight? Round to the nearest mi/hr.

Question

dillpickle · Answer

the answer is473 miles per hour

SourabhMa · Answer

The average speed of the wind is approximately 35 mi/hr.

SourabhMa · Answer

The average speed of the wind during the round trip flight from Chicago to London is approximately 35 mi/hr. The average speed of the jet was calculated to be around 478.79 mi/hr during the round trip. By setting up equations for the flight times and solving for wind speed, we found that the wind's effect is significant for the return trip.
