Answer :
To put these times in order from earliest to latest, let's first convert all the given times into a 24-hour format. This helps in comparing them easily.
A: 15:23 is already in 24-hour format. It is 3:23 PM.
B: 8:24 PM becomes 20:24 in 24-hour format.
C: 9:30 AM becomes 09:30 in 24-hour format.
D: 3:20 PM becomes 15:20 in 24-hour format.
E: 08:42 is already in 24-hour format. It is 8:42 AM.
F: 7:51 AM becomes 07:51 in 24-hour format.
Now, we list these times in order from earliest to latest by comparing their 24-hour time equivalents:
F: 07:51 (7:51 AM)
E: 08:42 (8:42 AM)
C: 09:30 (9:30 AM)
D: 15:20 (3:20 PM)
A: 15:23 (3:23 PM)
B: 20:24 (8:24 PM)
Therefore, the order from earliest to latest is F, E, C, D, A, B.
