<PRE><B>Question 1164163</B>
A non-stop flight between two cities averages 460(mph) and takes 2.5 hours. 
The nonstop flight back averages 500 miles per hour because of a tailwind.
 How long does the flight back take, assuming it follows the same flight path?
:
find the distance of the flight; dist = speed * time
460 * 2.5 = 1150 mi
find the return time when av speed was 500 mph; time = dist/speed
t = {{{1150/500}}}
t = 2.3 hrs
