Question

An airplane takes three hours to travel a distance of 1320 miles with the wind the return trip takes four hours against the wind find the speed of the plane in still air and the speed of the wind

Answer 1

106.6 mi/h, 26.6 mi/h

Explanation:

PRIMERO SE CALCULA LE VELOCIDAD CON EL VIENTO QUIETO

v =
`(320 mi)/(3 h)` = 106.6 mi/h

DESPUÉS SE ENCUENTRA LA VELOCIDAD DEL AVIÓN EN CONTRA DEL

VIENTO

v =
`(320 mi)/(4 h)` = 80 mi/h

FINALMENTE SE ENCUENTRA LA VELOCIDAD DEL VIENTO

v = 106.6 mi/g - 80 mi/h = 26.6 mi/h
