Question 1080617: A plane travels at a speed of 155⁢mph in still air. Flying with a tailwind, the plane is clocked over a distance of 950 miles. Flying against a headwind, it takes 3 hours longer to complete the return trip. What was the wind velocity?
I think I should have (950/(155-w)) - (950/(155+w)) = 3
but I'm unsure of what to do.

Initial table of data before analyzing the time quantities; w is tailwind speed.
               SPEED        TIME         DISTANCE

WITHWIND       155+w                     950
AGAINSTWD      155-w                     950

               SPEED        TIME            DISTANCE

WITHWIND       155+w        950/(155+w)      950
AGAINSTWD      155-w        950/(155-w)      950

Concentrate on the part of the description, Flying against a headwind, it takes
3 hours longer to complete the return trip.

This means .

The rest is arithmetic to solve the equation for , the speed of the wind.
