You can put this solution on YOUR website! A small plane flew 1030 miles in 5 hours with the wind. Then on the return trip, flying against the wind, it traveled only 730 miles in 5 hours. What were the wind velocity and the speed of the plane?
----
With-wind DATA:
distance = 1030 miles ; time = 5 hrs ; rate = 206 mph
----
Against-wind DATA:
distance = 730 miles ; time = 5 hrs ; rate = 146 mph
-------
Equations:
p + w = 206 mph
p - w = 146 mph
-----
Add and solve for "p"::
2p = 352
p = 176 mph (plane speed with no wind)
----
Solve for "w"::
Sutract and solve for "w":
2w = 60
w = 30 mph (wind speed)
