A jet plane traveling at 550 mph overtakes a propeller plane traveling at 150 mph that had a 3-hour head start. How far from the starting point are the planes?

The planes are 618.75 miles from starting point

Solution:

Let t is the travel time of the jet

Then  (t + 3) is the travel time of the propellar

When the jet overtakes the propellar, they will traveled the same distance

Distance is given as:

A jet plane traveling at 550 mph

propeller plane traveling at 150 mph

Equate both distance

Thus they are 618.75 miles from starting point
