Hi,
 Two trains leave Chicago at the same time traveling in <u>opposite directions</u>.
How long before they are 375 miles a part? 
One is going 60 miles per hour for{{{highlight(x)}}}mi  
and the other is going 65 miles per hour for {{{highlight(375m - x)}}}
Question states*** will travel the same amount of time and {{{t = D/r}}}
{{{x/60 = (375 -x)/65}}}  | Cross Multiplying to solve
 65x = 60(375-x)
 125x = 60*375
    x = 60*375/125 = 180mi, distance traveled by the 60mph train
 {{{t = 180mi/60mph}}} = 3hr
