You can put this solution on YOUR website!

Let "t" be the time after Dawn left the library.
Tara’s time at that moment is t%2B3+
Dawn will catch up with Tara when the distance is same.
14%28mil%2Fh%29%2At=8%28mil%2Fh%29%28t%2B3%29
14t=8%28t%2B3%29
14t=8t%2B24
14t-8t=24
6t=24
t=4
Dawn will catch up with Tara in 4 hours.
