Question

a jet plane traveling at 500mph overtakes a propeller plane traveling at 200mph that had a 2 hour head start. how far from the starting point are the planes

Answer 1

D$D_{1} = D_{2}$
500(x-2)=200x 
500x-1000=200x
300x=1000
x=3.333330 or 3 and 1/3

Propeller distance: 3 and 1/3 * 200 = 666.666667 or  666 and 2/3 miles
