Homework Help: math(rational functions application)

Posted by jane on Thursday, October 22, 2009 at 6:23pm.

The average speed of a jet is 100km/h faster than a cargo plane. To travel 1400km, the cargo plane requires 25% more time than the jet. Find the average speed of the jet.

This is the formula I figured out so far.

V(average)=V(jet)-V(cargo
100km/h= d/t - d/t
100= [1400km/x] - [1400/(.25x+x)]

But from here I don't know what to do..
