Return trip took 1 hr. and 50 min.
What was the speed of the wind?
What was the speed of the plane in still air?

Use the formula speed =distance / time

130 minutes = 2 hours and 10 mins,
130 mins x (1hr / 60 mins) = 13/6 hr

1 hr and 50 minutes = 110 mins
110 mins x (1hr / 60 mins) = 11/6 hr

Speed for plane ...
