Question 818217: [ A plane flies 3600 miles from San Francisco to Tampa Bay in 8 hours, with a tailwind all the way. The return trip on the same route, now with a headwind, takes 9 hours. Assuming both speeds remain constant, find the speed of the plane and the speed of the wind. ] Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! s = d / t
---
outbound:
s + w = 3600/8
s + w = 450
---
return:
s - w = 3600/9
s - w = 400
s = 400 + w
---
s + w = 450
400 + w + w = 450
2w = 50
---
w = 25 mph
s = 425 mph
