**Reiny**, Sunday, November 22, 2009 at 12:41amlet the time passed from 9:32 til train B catches up to A be t hrs.

When B passes the station, train A will have traveled 12 minutes at 40 mph or 40(12/60) miles or 8 miles.

So when B catches A,

train A is (8 + 40t)miles past the station

train B is 50t miles past the station

but these two distances are the same, so

50t = 8 + 40t

10t = 8

t = 8/10 hours = 48 minutes

so the meet at 9:32 + 0:48

= 10:20 am
