Question 681960
A plane flew 500 km from Atlanta, GA, to Louisville, KY.
 When returning to Atlanta, the flight took ½ hour less time.
 If the rate to Louisville was 50 km/hr slower than the rate returning, find the two rates in km/hr. 
:
s = speed to Louisville
then
s + 50 = speed back to Atlanta
:
Write a time equation; time = dist/speed:
:
To time - return time = 1/2 hr
{{{500/s}}} - {{{500/((s+50))}}} = .5
