17.30 hours is after noon. therefore you subtract 12.00 away from it. so it's 5.30 pm.

17.30 hours = 17 hours and 3/10 x 60mins
17.30 hours = 17 hours and 18 minutes
17.30 hours = 5 :18 pm
HOWEVER the question may have been presented incorrectly and should perhaps be
17:30 which is 5:30 pm

17:30 hours is 5:30 PM.
It is very simple to break down...
You have a 12 hour time system, and a 24 hour time system.
The 12 hour time system is divided into 2...meaning AM and PM. (Remember that 12 +12 equals 24!) The 24 time system is just that...24 hours in a day.
So for example, at 12:00 AM (Midnight) your at 00:00 (or 24:00). At 1:00 AM your at 01:00...and so on. When you get to 1:00 PM however, your at 13:00 hours. They call it Military time to avoid the AM and PM.
So 19:00 hours would be 7:00 PM. 20:20 hours would be 8:20 PM. You just continue to count upwards until you hit midnight and it goes back to 00:00 hours (or 24:00 hours)
Remember that there are 24 hours in a day! Hope that helpled!

17.30 hours is a military form of time... you just continue counting after 12 to 13, 14, 15 etc after noon time... therefore 17 is 5 o'clock and the 0.3 of an hour can be identified using the clock problem formula,
H = m / 60 where H is the is the travel of the short hand of the clock in a 1 hour duration, and m is the travel of the minute hand of the clock in a 1 hour duration...
therefore...
to get the exact time of 0.3,
H = m / 60
0.3 = m / 60
m = 0.3 (60)
m = 18 mins
so,
17.30 hours means
5 o'clock and 18 minutes.

It is the 24 hour system.
00:00 is mid night.
12 hours later is noon 12:00 hours.
You add one hour on to 12:;00 for a later time.
1 o'clock is 13:00 hours.
17:30 hours would be 12:00 plus 5 17:00 .plus 30.
1 o'clock in the morning would be 01:00 hours etc.

1200 hours is noon so every 100 after is an hour so 17.30 is 5.30 at night or just -12 hours

17.30 Military Time

for any time after 12 noon, always subtract 12 from the given time, and the answer is the time after noon.
for example, 17.30 hrs-12=05.30
therefore, the time is 05.30 p.m.(after noon)

If you have trouble subtracting 12, subtract 2 and drop the 1st digit. What is best, is to know that 17:30 is evening and 05:30 is morning. Do not convert to AM and PM.

It is military time. When you watch movies and you hear the seargent screaming, "I want you boys up at 0400 hours, it means he wants them up at 4AM. Just think of it as starting the clock at 0000 at midnight and proceeding all the way to 2400 (which is the end of day and it goes back to 0000). So if you had a date with a girl at 8pm, it would be 2000 hours, (Start from 0000 (midnight) add 20 to the front two digits and your home.

to answer the question that would be 5:30 in the afternoon
as to how i came up with the answer, it has been the convention that anything that goes beyond the twelve o'clock mark is counted straight to 24.
i.e.
13 = 1 pm
14 = 2 pm
etc...
