hi,
Let x be the speed of the car
.
Question states
%28240%2F880%29+=+%28xmph%2F%28x+%2B+160mph%29%29
.
cross multiply to solve
880*x = 240*x + 38400
640*x = 38400
x = 60mph (the speed of the car
.
speed of the plane is 220mph (160mph faster than the car)
.
check your answer
takes plane 4 hrs to travel 880mi
and 60mph*4hrs = 240mi
