Question 1196331
.
The Marketing Executive Problem: A marketing executive traveled 810 miles on a corporate jet in the same amount 
of time that it took to travel 162 mi by helicopter.  The rate of the jet was 360 mph greater than the rate of 
the helicopter.  Find the rate of the jet.
~~~~~~~~~~~~~~~~~~~~~~


<pre>
Start writing "time" equation as you read the problem

    {{{162/x}}} = {{{810/(x+360)}}}


Cross multiply, then simplify

    162(x+360) = 810x

    162x + 58320 = 810x

    58320 = 810x - 162x

    58320 =    648x

      x   =    58320/648 = 90.


Thus the helicopter's rate is 90 miles per hour.


Then the jet's rate is  90 + 360 = 450 miles per hour.    <U>ANSWER</U>
