Uhm read the highlighted. I already answered the first one (as you can tell its C) I just need help with the last one :D

He added all the numbers as they were a decimal number, with the kilometers traveled by Bus and Car being 2 to the left than where it should have been.

How I found it:

Converting 7 and 2.3 into a decimal with the decimal place two to the left.

7 becomes 0.07

2.3 becomes 0.23

I added this to the kilometers traveled by train(which is 19.955km).

19.955km + 0.023 + 0.07 = 19.985

19.985 being the value for answer A.

Hope that helps :)
