Question 1059478: A plane has a cruising speed of 200 miles per hour when there is no wind. At this speed, the plane flew 500 miles with the wind in the same amount of time it flew 300 miles against the wind. What is the speed of the wind? Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Let w be the speed of the wind. Then:
500/(200+w)=300/(200-w)
60000+300w=100000-500w
800w=40000
w=50 mph as the speed of the wind. ☺☺☺☺
