let the speed of the wind be x mph

so the speed of the plane with the wind is 220+x

and against the wind it would be 220-x

The time taken against the wind is 780/(220+x)

and the time taken with the wind would be 780/(220+x), remember Time = Distance/Rate

but we are told their times are the same

so 780/(220+x) = 780/(220+x)

I will leave the arithmetic up to you,

(I got x = 40)
