Question 814603: A train travels 220 miles and returns the same distance. The total time taken by the train is 9 1/2 hours. If the speed of the train averaged 15 miles per hour more while going back, how fast did the train travel in each direction?

You can put this solution on YOUR website! G+R=9.5,
r=g+15,
G*g=220,
R*r=220
going speed g = 40, going time G = 5.5,
return speed r = 55, return time R = 4
40*5.5=220
55*4=220
ok
