Yay, I love rate problems!

Noon is 12:00 PM. 

So train A leaves at 12:00 PM and drives at 90 mph (I know right? CLASS 5 PASSENGER THAT'S LUXURY). And train B leaves from the same place and drives from the same direction at 10 mph greater than 90mph. In 30 minutes 12-12;30, Train A will go 45 miles and Train B will go 0 miles (Not left yet). In another 30 minutes, a total of 1 hour, Train A will have went 90 miles and train B will go 50. 2 hours, 180 miles VS 150 miles. 4 hours, 360 miles VS 350 miles. And 5 hours will add a total of 10 miles difference, which is 450 vs 450!!! Therefore 12:00+5:00=

 

17:00 in 24 hour clock

and 5:00 PM in 12 hour clock!
