# Thread: Central Standard Time (CST)

1. ## Central Standard Time (CST)

The current time is 12 noon CST. What time (CST) will it be 12, 997 hours from now?

Let me see...

Note: 12 noon means 1/2 of 24 hours.

1. Must I add 12 hours to 12, 997 hours?
2. If step 1 is correct, what should I do next?

One method for helping you solve problems is to simplify the problem at first.

The current time is 12 noon CST. What time (CST) will it be 25 hours from now?

The current time is 12 noon CST. What time (CST) will it be 26 hours from now?

The current time is 12 noon CST. What time (CST) will it be 50 hours from now?

Now try the original problem again.

There are 24 hours in a day. If you divide 12,997 by 24 what is the remainder? What does that tell you?

Well, 24 hours from now will be 12 noon the next day. If one more hour is added, we arrive at 1 pm the next day.

The current time is 12 noon CST. What time (CST) will it be 26 hours from now?

Note: 24 hours from 12 noon today takes use to 12 noon tomorrow. Adding two more hours we arrive at 2pm the next day.

The current time is 12 noon CST. What time (CST) will it be 50 hours from now?

12 noon today + 50 hours takes us to 2 days later plus 2 hours. That is, we arrive at 2pm two days later.

12,997 ÷ 24 = 541, remainder 13. The remainder tells me nothing.

Beg your pardon, it tell you every thing. Thirteen hours from noon is 1am.
Now this does not adjust for daylight saving time changes.
We would have gone through 541 twenty-four hour plus thirteen more hours.

After dividing, I did not know what to do with the decimal number.

You said:

"We would have gone through 541 twenty-four hour plus thirteen more hours."

So, 541 twenty-four hours = 541 days later
Of course, we must add 13 more hours taking us to 1 am over one year later.

Plato:

I did not know that the remainder of 13 describes hours.

Pray tell. what else could the the 13 represent?

I thought 13 represented minutes or seconds.

Go back to the 3 leading questions I gave you in post #2.

1. When you divide 25 hours by 24, the remainder is 1 hour.
2. When you divide 26 hours by 24, the remainder is 2 hours.
3. When you divide 50 hours by 24, the remainder is 2 hours.

The process is the same for 12 997 hours.

12 997 hours /24 = 541.541666... hours = 541 full days + 0.541666..days = 541 days + 0.541666 x 24 hours = 541 days + 13 hours.

In other words, 12 997 hours = 541 x 24 + 13 hours.

I think the red shows where you had a problem.
