The wind speed was 100 km / h, and the average speed of the plane was 800 km / h.
Since an airliner traveling from Paris to Toronto took 7 h to cover the 6300 km trip with a tailwind, and the return trip, traveling against a headwind took 9 h, to find the wind speed and the average speed of the plane, the following calculation must be performed:
- 6300/7 = X
- 900 = X
- 6300/9 = X
- 700 = X
- (900 - 700) / 2 = X
- 200/2 = X
- 100 = X
- 700 + 100 = 800
- 900 - 100 = 800
Therefore, the wind speed was 100 km / h, and the average speed of the plane was 800 km / h.
