A jet's speed in still air is \( 240 mph \) . One day it flew \( 700 \) miles with a tailwind and then returned the same distance against the wind. The total flying time was \( 6 \) hours. Use the following equation to find the speed of the wind (w). 

\( \frac { 700 } { 240 + w } + \frac { 700 } { 240 - w } = 6\)
