**jai**, Tuesday, August 31, 2010 at 9:26pmlet x = time it takes for them to be 45.6 miles apart (in hours)

recall: (speed)*(time)=distance

>>since they travel in opposite directions, the distances between the station to their present location will be added.

10x + 9x = 45.6

19x = 45.6

x = 2.4 hours

so there,, =)
