You can put this solution on YOUR website! A passenger plane and a jet leave at the same time from the same airport, traveling in opposite directions.
The jet travels at twice the speed of the passenger plane.
They are 2400 miles apart in 4 hours.
Find the speed of the passenger plane and jet.
:
Let s = pass plane speed
It say's,"The jet travels at twice the speed of the passenger plane.", therefore:
2s = jet plane speed
:
Write a distance equation, Dist = speed * time;
4s + 4(2s) = 2400
You should be able to find s
