You can put this solution on YOUR website! A certain aircraft can fly 1330 miles with the wind in 5 hours and travel the same distance against the wind in 7 hours.
What is the speed of the wind?
----
With-wind DATA:
distance = 1330 miles ; time = 5 hrs ; rate = d/t = 1330/5 = 266 mph
-----
Against-wind DATA:
distance 1330 miles ; time = 7 hrs ; rate = d/t = 1330/7 = 190 mph
-----------------
Equations:
Let p be plane speed in still air.
Let w be wind speed.
------------------
p + w = 266 mph
p - w = 190 mph
-----
Subtract to solve for wind speed:
2w = 76
wind speed = 38 mph
