How long do you live?

How Long You Really Live

Hi, my name is Angelina, and I’m going to teach you how many hours you live, how many minutes you live, how many days you live, etc.
            Everybody lives for about 75 years in a lifetime. To find out how many days you live, you would do 75 (years you live) x 365 (days per year), and it equals 27,375. Therefore, you live for about 27,375 days. To find out how many hours you live, you would have to multiply 27,375 (days you live) by 24 (hours per day), to equal about 657,000 hours in your lifetime. Next, do 657,000 (hours you live) by 60 (minutes per day) to find out how many minutes you live, and 657,000 x 60 = 39,420,000 minutes in an average lifetime. Finally, multiply 39,420,000 (minutes in a lifetime) by 60 (seconds per day) to equal 2,365,200,000 seconds you live in your lifetime.

Here is the chart to show you how many years, days, hours, minutes, and seconds you live:


Years

Hours

75
27,375
657,000
39,420,000

Maybe you can come up with the next 50...or maybe not! :)

How Many Seconds?

Hi I'm Will. I was interested in how many seconds were in different periods of time. So I figured it out.

1 minute = 60 seconds
1 hour = 3,600 seconds
1 day = 8,640 seconds
1 week = 604,800 seconds
1 year = 31,556,926 seconds
5 years = 157,784,630 seconds
10 years = 315,569,260 seconds
50 years = 1,577,846,300 seconds
100 years = 3,155,692,600 seconds
1,000 years = 31,556,926,600 seconds
10,000 years = 315,569,260,000 seconds
100,000 years = 3,155,692,600,000 seconds

WOAH!

What do you notice? Do you see any patterns? How did I figure this out?

Read This! Monster Money Book

I'm Miranda and I read Monster Money Book by Loreen Leedy.

The Monster Money Book

This book is mostly about money. It talks about how to save money and teaches you different money vocabulary like deposit and savings. It also teaches how to add money and coins. This is a good book if you want to learn how to be money smart.

Roman Numeral Fun

Here are some common Roman Numerals:

I = 1
II = 2
III =3
IV = 4
V = 5
X = 10
XII = 12
L = 50
C = 100
D = 500
M = 1,000

You can even do basic math with Roman Numerals:

I x L = L (50)
X + X = XX (20)
L + C = LC (150)
I + V + X = XVI (16)

These are Roman Numerals. Usually Americans would use Arabic Numerals (1, 2, 3...) but there's an older number system, it's Roman Numerals! They were made in Greece. Even though we normally use Arabic Numerals, we sometimes see Roman Numerals. For example: we write World War I and World War II instead of World War 1 and World War 2. Using Roman Numerals can be fun, give it a try!
