An ordinary plane leaves an airport and flies due west at 180kph. Two hours later a jet leaves the same airport and flies due west at 900kph. How far from the airport will the jet overtake the ordinary plane?

Answered by bobpursley
distance traveled is the same
plane1:
d=180*t
Plane2
d=(900)(t-2)
set them equal
180t=900t-1800
solve for time t, then go solve for d in either equation.
