A plane traveling a distance of 660km, with unknown speed, has a tail wind of 60km/h, and due to this tail wind arrives at its destination 6 mins early.
What is the speed of the plane without the wind?
Homework Equations
I have so far used s=d/t,
The Attempt at a Solution
Using s=d/t, i have got expressions for both s and t.
s = (x + 16.7) m/s
t = (x' +360) s and i have converted 660 km into metres, 660000m to get
x + 16.7 = 660000/(x' + 360)
However i am not sure if this is the right way of looking at it, so any help will be greatly appriechiated.
Thanks
John
