Final answer:
The number of zeros that can be written in a day is 172,800.
Step-by-step explanation:
To determine how many zeros can be written in a day, we need to convert 1 minute to seconds and then multiply it by the number of seconds in a day. There are 60 seconds in a minute and 24 hours in a day. So, the calculation becomes: 120 zeros/minute x 60 seconds/minute x 24 hours/day = 172,800 zeros/day.
