Please repost with the complete statement of the problem.

Need to know how long was the return trip against the wind.

R is the speed of the plane.

S is the speed of the wind.

T is the TOTAL time in hours

There are two equations:

Distance = rate x time

= (R + S) x 1.5 <--- with the wind

= (R - S) x (T- 1.5) <--- against the wind

Note that 90 min - 1.5 hours
