**bobpursley**, Thursday, September 11, 2008 at 7:44pmthe distance traveled is the same

distancefirst=32*time

distancesecond=52*(time-2)

set them equal, solve for time.

**Pat**, Thursday, September 11, 2008 at 8:34pmI think i may have found out teh right answer but a little different then you did. Can you check this and tell me if im right pls?

I got 3.2 hours as my answer.

the way i did it was more of drawing it out then eqaution.

when the 2nd train starts the 1st is already 64km away. Every hour after that the 2nd train catches up 20km.

From there i divided 64/20 which is 3.2.
