An airplane can travel 550mph in still air. If it travels 3498 miles with the wind in the same length of time it travels 3102 miles against the wind, what is the speed of the wind?

Respuesta :

Speed of the airplane for the wind is 583 mph and speed of the airplane against the wind is 517 mph

Given that the speed in still air is 550mph, then we can say that

speed for the wind = 550 + w

speed against the wind = 550 - w

Considering that it travels 3498 miles for the wind and 3102 against the wind, we can then say that

3498/(550+w) = 3102/(550-w)

if we cross multiply, we have

3498 × (550-w) = 3102 × (550+w)

1923900 - 3498w = 1706100 + 3102w

collecting like terms

1923900 - 1706100 = 3102w + 3498w

217800 = 660w

w = 217800/660

w = 33

If w = 33, then the speed for and against the wind is 550+33 = 583 mph and  550 - 33 = 517 mph respectively.
