With a headwind, a plane traveled 390 mi in 1.5 h. Let x represent the plane’s speed (excluding wind speed) and let y represent the wind speed in miles per hour.
Which equation models this situation?
A.390 = 1.5x – 1.5y
B.390 = 1.5x – y
C.390 = 1.5x + 1.5y
D.390 = 1.5x + y

Best ResponseYou've already chosen the best response.1speed times time = distance speed into the wind is xy (the wind slows you down) so 390= 1.5(xy) or if you distribute 390= 1.5x  1.5y
