When the jet plane starts to move the propeller plane was already flying for 4 hours thus they have a gap of 1000 milles.

if they will meet after a time of x hours then the distance for both will be 1000 +250x = 550x

solve this equation and find the time x=10/3 Hours

multiply this by 550 and you will find 1833milles ..
