Question 1196331
<br>
The distances are 810 and 162 miles, and the times are the same, so the ratio of the two speeds is the same as the ratio of the distances -- 810:162 = 5:1.<br>
Knowing that ratio, let the speed of the jet be 5x and the speed of the helicopter x.  The difference between the two speeds is then 4x.<br>
But the difference in the two speeds is 360mph; so 4x = 360 and x = 90.<br>
So the speed of the helicopter is x = 90mph and the speed of the jet is 5x = 450mph.<br>
ANSWER: 450mph<br>
