A private airplane leaves Midway Airport and flies due east at a speed of 180km/h. Two hours later, a jet leaves Midway Airport and flies due east at a speed of 900km/h. How far from the airport will the jet overtake the private plane?
-----------
In 2 hours, the slow plane is 360 km away.
The speed of the jet relative to the slow plane is 720 km/hr (900 - 180)
It will overtake the slow plane in 1/2 hour (360/720)
900 * 1/2 = 450 km from the airport
