Question 19996: It takes a small jet plane 4 hours less time than it takes a propeller-driven plane to travel from Glen Rock to Oakville. The jet plane averages 637 km/h while the propeller plane averages 273 km/h. How far is it from Glen Rock to Oakville?

Let t be the distance
637(t-4)=273t
637t-2548=273t
-2548=-364t
t=7
Therefore the distance between them is 7 km.
