Question 1093863
It takes a plane two hours to fly from Detroit to New York and only an hour and thirty minutes to return. If the wind speed is 25 mph. How far apart are the two cities?
===========
You didn't spec the wind direction.
Assuming it's a direct headwind and tailwind:
---
d = distance in miles
a = plane's airspeed in mi/hr
---
d = 2*(a-25) = 1.5*(a+25)
2a-50 = 1.5a+37.5
0.5a = 87.5
a = 175 mi/hr
=======================
d = 300 miles
