"GRE MATH PROBLEM OF THE DAY"
At 10 a.m. two trains started traveling toward each other from stations 287 miles apart. They passed each other at 1:30 p.m. the same day. If the average speed of the faster train exceeded the average speed of the slower train by 6 miles per hour, which of the following represents the speed of the faster train, in miles per hour?

C
please tell how to do this problem
the average relative speed of the trains is 287/3.5 = 82
Let the speed of the slower train be x
then relative speed = x + (x+6)
or, 82 = 2x+6
==> x = 38
hence speed of the faster train = x+6 = 44
YA CORRECT ANS IS C
CONGRATS ZUBER KHAN UR EXPLAINATION IS ABSOLUTELY CORRECT
C
its 44
thank u zubr u r geneous u gve d correct trick for this questn.
