Question 1199975
A military drone can fly at 7 miles per hour in calm conditions. For one flight, the drone flew 54 miles with the wind and 30 miles against the wind in the same amount of time. What was the wind speed for the flight?
----------------------------
w = wind speed
===

t*(w+7) = 54
t*(w-7) = 30
---
tw + 7t = 54
tw - 7t = 30
---------------------- Add
2tw = 84
tw = 42
------
42 + 7t = 54
7t = 12
t = 12/7 hours
=====
w = 42/t = 294/12 = 24.5 mi/hr
======================================
The launch was not a good idea.  The drone is miles away and can't return against the wind which is 3.5 times its airspeed.
