Question

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

Answer 1

A Is my answer

Answer 2

do you understand by mean headwind

Answer 3

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

Answer 4

yup @phi is right

Answer 5

Thanks you
