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

    speed times time = distance speed into the wind is x-y (the wind slows you down) so 390= 1.5(x-y) or if you distribute 390= 1.5x - 1.5y
