Step 1:I'll solve this step by step, carefully following the LaTeX formatting guidelines:
Step 2:: Convert days to hours
21 \text{ days} \times \frac{24 \text{ hours}}{1 \text{ day}} = 504 \text{ hours}
Step 3:: Convert days to minutes
21 \text{ days} \times \frac{24 \text{ hours}}{1 \text{ day}} \times \frac{60 \text{ minutes}}{1 \text{ hour}} = 30,240 \text{ minutes}
Step 4:: Convert days to seconds
21 \text{ days} \times \frac{24 \text{ hours}}{1 \text{ day}} \times \frac{60 \text{ minutes}}{1 \text{ hour}} \times \frac{60 \text{ seconds}}{1 \text{ minute}} = 1,814,400 \text{ seconds}
Step 5:: Compare to weeks
21 \text{ days} = 3 \times 7 \text{ days} = 3 \text{ weeks}
Step 6:: Compare to months
A typical month is approximately 30 days, so 21 days is less than 1 month.
