100 m
If the length of a train is 50m, then the length of track that the train travels on must also be 50m. If there are two trains, each 50m long, then the sum would be:
50 + 50 = 100
The two trains occupy 100 m of track at any given time.

To make it easier, add each amount separately:
3 hours + 3 minutes = 3h30m
3 hours and 30 minutes + 2 hours = 5h30m
5 hours and 30 minutes + 30 minutes = 6h
6 hours + 2 hours = 8 hours
399 + 46 + 11
399 + 46 = 445
And
445 + 11 = 456
