A train leaves the station at 8 a.m. and averages 40 miles per hour another train leaves the same station one hour later and averages 50 miles per hour traveling in the same direction on a parallel track at what time will the second train catch up with the first train how many miles would each train traveled by that time?

the first train is 40 miles ahead when the 2nd train starts.

The 2nd train is going 10 mi/hr faster, so how long do you think it will take to cover the extra 40 miles?
