Question 1055127
.
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.
~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Your equation is

{{{1500/(s+70)}}} = {{{1290/s}}}

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

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

The rest is just arithmetic.
