Answer 3

Calculating the Time Spent in the Train

To calculate the time Professor Seleznyov spent in the train, we can subtract the time he entered the train from the time he exited the train.

Time Entered the Train: 19:00 Time Exited the Train: 19:00 the following day

To find the time spent in the train, we can subtract the time he entered the train from the time he exited the train:

19:00 (next day) - 19:00 = 24 hours

So, Professor Seleznyov spent 24 hours in the train.
