Big plane. A six-passenger plane cruises at 180 mph in
calm air. If the plane flies 7 miles with the wind in the
same amount of time as it flies 5 miles against the wind,
then what is the wind speed? Answer by checkley77(12569) (Show Source):
You can put this solution on YOUR website! D=RT OR T=D/R
T=5/(180-W) SEEING AS THE TIMES ARE EQUAL WE SET THESE 2 EQUATION EQUAL
W=30 MPH.IS THE WIND SPEED.
