Question

When using the 24 hour clock, 5:15 p.m is: A. 0515 hours B. 1515 hours C. 1715 hours D. 2015 hours

Answer 1

On a 24 hour clock or military time clock. 5:17 p.m would be 17:15 on a military or 24 hour clock. So the answer is C., the 17(:)15 hours.

Answer 2

C

Explanation:

An expression for this would be 12:00+x=y

X represents what time it is in 12 hour time and y represents the overall time in a 24 hour standard. All you need to do is add 12 hours to the time IF IT IS PAST NOON because anything before that is normal time (as in the same as 12 hour standard).
So we can substitute x for 5:15 and solve.
12:00+5:15=y

Combine like terms

17:15=y

So our variable y is 17:15, and since our y variable represented the time in a 24 hour standard, the time in a 24 hour standard would be 17:15.
I hope this helps!!!
