Google Spreadsheets SUM – Getting SUM Function to Work in Google Spreadsheets

google sheets

I'm trying to get something like this. These are all in minutes I guess it goes that way when I type them like this.

Number     Time     After Work      TOTAL
1          1:52       2:00         (Result Of Course)
2          3:54       2:00 
3
4
5

I'm trying to get to plus/add all the "time" plus "afterwork" divided by the number that has a registered value like 1 and 2. I don't know how to use excel (I don't know the terms or what the right formula is called).

I'm completely illiterate about this stuff and I really can't get through the formula explanations, tried couple of stuff but unfortunately failed that's why I'm here, hopefully I can get an answer right away

Assuming Number is in A2, Time B2, after work in C2 and the total in D2, put the following formula in D2

=(B2+C2)/A2

Copy the formula in D2 to D3, D4 etc

Here's an example
