Use algebra with the fact the Distance (d) = Rate (r) times time (t) and further you do know that the distance traveled by each plane was equal at the point where jet overtook the prop plane.
Let t = time of Jet plane flight at the point of overtake.
Let t + 4 = time of prop plane flight (from start to overtake point)
The distance for each plane is equal, and furthermore we know that d=rt.
Step 1. calculate distance of Jet plane. d=rt, so d=550 t
Step 2. calculate distance of prop pland d=rt, so d=200(t + 4) = 200t + 800
Since the distances are equal, Step 3. Set up the equation:
550t = 200t + 800 Now solve for t and calculate the distance which is the answer that is being sought. d=rt Use the Jets rate and time. and then verify by solving for distance of the prop (using t + 4) Both distances should be equal verifying the correctness of your answer.
