here it is:

An Airliner travels 1432 miles in four hours, flying with the wind. on its return trip, it took five hours flying against the same wind to go 830 miles. how fast would the plane have flown without any wind; i.e. the speed in still air?

a. 81 mph

b. 86 mph

c. 91 mph

d. 96 mph

Any way I plug it in i'm not getting the #'s to work - how do I figure this out??
