Answer 1

Answer:

1 min and 23 seconds

Step-by-step explanation:

I calculated this by trying to solve how many minutes and seconds it would take for 29 mins 50 secs to get to 31 mins 13 secs.

The first thing I did was add 1 minute. This would make the time become 30 mins 50 secs.

I then tried to find how many seconds it would take to make it become 31 minutes, which is 10 seconds (since 50 seconds + 10 seconds = 1 minute).

Then I added 13 seconds because that's how you get from 31 minutes to 31 mins and 13 seconds. 13 + 10 = 23

Finally, the answer is 1 minute and 23 seconds.
