a jet plane travelling at 500 mph over takes a propeller plane travelling at 200 mph that had a 2-hour head start.how far the starting point are the planes?
Upon overtaking the propeller plane, the jet and propeller planes would’ve traveled the same distance
Let the distance traveled by both planes, to the meeting point, be D
Then time taken by propeller plane to travel to planes’ meeting point = 
Time taken by jet plane to travel to planes’ meeting point = 
We therefore have: 
5D = 2D + 2,000 ------- Multiplying by LCD, 1,000
5D – 2D = 2,000
3D = 2,000
D, or distance traveled by the planes, or distance from starting point = , or miles
You can do the check!!
