Ok, since the minutes here are 30, all we need to do is simply add 25 minutes to our time.

3:30

Now 30 + 25= 55

So our final time he finished: 3:55

If you would like to know what time did Mario finish his homework, you can calculate this using the following step:

3 (hours) : 30 (minutes)  + 25 minutes ... 3 (hours) : (30+25) (minutes) ... 3 (hours) : 55 (minutes) ... 3:55

The correct result would be 3:55.
