An aircraft travels with the wind for 120 miles in 0.75 of an hour. the return trip is flown against the wind and takes exactly 1 hour. which system of linear equations represents x, the speed of the plane in miles per hour, and y, the speed of the wind in miles per hour? recall the formula d = rt. 0.75(x + y) =β120 x β y =β120 0.75(x β y)=β120 x + y =β120 120(x + y)β=β0.75 120(x β y)β=β1 120(x β y)β=β0.75 120(x + y)β=β1 mark this and return
