30 seconds is half a minute, so to express it as a percent of a minute, you would write it as 50%.
To express 30 seconds as a percent of a minute, you can follow these steps:
Step 1: Convert 30 seconds to minutes.
30 seconds ÷ 60 seconds/minute = 0.5 minutes

So, 30 seconds is equivalent to 50% of a minute.
To express 30 seconds as a percent of a minute, you need to calculate the fraction of a minute that corresponds to 30 seconds and then convert it to a percentage.
First, you need to know that there are 60 seconds in a minute. So, to find the fraction of a minute that is equal to 30 seconds, you divide 30 by 60:
30 seconds / 60 seconds = 0.5 (fraction)
Now, to convert this fraction to a percentage, multiply it by 100:
0.5 x 100 = 50%
Therefore, 30 seconds is equal to 50% of a minute.
