A commercial jet travels 1500 mi in the same amount of time it takes a corporate jet to travel 1290 mi.
The rate of the commercial jet is 70 mph greater than the rate of the corporate jet. Find the rate of each jet.
~~~~~~~~~~~~~~~~~~~~~~~

Your equation is

1500%2F%28s%2B70%29 = 1290%2Fs

where s is the rate of the slower (=corporate) jet (in mph).

Multiply both sides by s*(s+70).

The rest is just arithmetic.
