**bobpursley**, Monday, May 24, 2010 at 9:11amtime= distance/speed.

3hrs= d/50 + x/60

2hrs 52min= d/60 + x/50 or

172/60 hrs= d/60 + x/50

I would multiply the first equation by 50, the second by 60

3*50=d-50x/60

172=d-60x/50

subtract the second from the first.

150-172=x(5/6-6/5)

solve for x.

Then, put x in either equation, solve for d. you are looking for x+d
