The answer is:
Reasoning:
$17:45 + 22:05 = 1510$
$20:55 - 17:30 = 35$
$06:40 ∗ 19:20 = ?$

The number you're looking for is:
The three digit number $x$ is:
The two, two digit numbers ($y$ and $z$) are:
The one digit number is:
Concatenating these together gives us:
Note: I brute forced my answer since the no-computers tag wasn’t specified.
