Final answer:
The duration from 48 to 72 days is a simple subtraction problem, resulting in a duration of 24 days.
Step-by-step explanation:
The question asks to find the duration between two numbers, specifically from 48 to 72 days. Calculating duration in this context is a straightforward subtraction. To find the duration, we subtract the smaller number (48) from the larger number (72).
Duration = 72 days - 48 days = 24 days.
Therefore, the duration from 48 to 72 days is 24 days. This is a simple mathematical calculation part of the subject area of mathematics, appropriate for a middle school level understanding of subtraction.
