Time - Applying Time

You have learned about Time.

Today, we will learn how to apply Time in our daily lives.

There are a few things you must know about Time:




1 Day = 24 Hours
* Notice the short needle will rotate from 0 to 12 for 2 rounds to reach 24 Hours

1 Hour = 60 Minutes
* The long needle will rotate from 0 to 12 for 1 round to reach 60 Minutes

1 Minute = 60 Seconds
* The red needle will rotate from 0 to 12 for 1 round to reach 60 Seconds


To apply Time in our daily lives, here is an example:
Kamal got onto a bus ride from his house to school at 6.50 o'clock. The journey took 20 minutes. What time Kamal reached the school?

     06 50
+   00 20
     06 70 - BUT 1 Hour = 60 Minutes
So: 07 10 - 70 Minutes - 60 Minutes = 10 Minutes

Answer: Kamal reached the school at 7.10 o'clock.

If Raju went into the shop at 9.55 and came out 10.05, how long was he in the shop?

     10 05
-    09 55
     00 10 - 1 Hour = 60 Minutes

Step by step answer:
     09 65
-    09 55
     00 10

Answer: Raju was in the shop for 10 minutes.

Remember the lesson well. Thank you.
