Question 364095: **A plane takes 6 hours to fly from San Francisco to New York, and 5 hours to return back. The airplane's airspeed is 550 miles per hour, from New York to San Francisco. The reason why it takes the airplane longer to go West than East is because of a wind with constant wind speed. What is the speed of wind? ( the answer with steps)

Let x = the speed of wind in mph
distance = airspeed x travel time
= airspeed x travel time from San Francisco to New York
= airspeed x travel time from New York to San Francisco
550 * 5 = (550-x-x) * 6
2750 = 3300 - 12x
12x = 3300 - 2750
12x = 550
x = 45.83
The speed of wind is 45.83 mph
