The time is 4:00 PM.
8 hours left in the day and 16 hours already passed.
To solve,
Hours left is a, so hours already passed = 2a.
We know a + 2a = 24
3a = 24
a = 8
2a = 16
So, time is 4 PM.

To determine how many half-lives have passed, you would need to divide the total time passed by the half-life of the substance. The result would give you the number of half-lives that have occurred.
It's 2 and a half hours, you've already answered it!
If ' L ' is the number of days in one half-life, then the number of half-lives in 32 days is (32 / L) .
The number is already rounded to a greater extent than that!
24
Whole numbers are already rounded to the nearest half.
276 hrs (11.5x24)
There is 30 minutes in a half hour. There is no hours in half hours.
100 and half a body
1/16 remains 12 hours is 1/2 24 hours is 1/4 36 hours is 1/8 48 hours is 1/16
since there are seven days in one week there cannot be an integer number to the days in half of a week, however one half of a week would be 3.5 days. True story.
There are 5 half hours in 2.5 hours
