First, we need to calculate the time it would have landed if it wasn’t late.
14:54 + 4:10 = 18:64
There are 60 minutes in an hour, so we need to amend our time.
18:64 => 19:04
If the plane wouldn’t be late, it would have landed at 19:04.
Although it was late, so we need to add the extra 12 minutes to the landing time.
19:04 + 00:12 = 19:16
The plane landed at 19:16.
