Change 1 h 25 min 29 s to s.

The total is 5,129 seconds

Step-by-step explanation:

Since we are already have the seconds, we need to convert the hours into minutes because this process will be easier.

Step 1:  Convert the hour into minutes

1 hour = 60 min

1 * 60

60

We have 1 hour so, now we have 60 minutes

Step 2:  Convert all of the minutes into seconds

25 + 60

85 total minutes

1 min -> 60 sec

85 * 60

5,100 sec

So we have 5,100 seconds that was produced from the 1 hour and 25 minutes, now we need to add this to the original seconds, 29.

Step 3:  Add up all of the seconds

5,100 + 29

5,129

So, we have a total of 5,129 seconds that was produced from the time given.

 The total is 5,129 seconds
