For example: The time interval between 12 o’ clock and 1 o’clock is 1 hour. Conversion of Minutes into Hours: Follow the given steps

• Divide the number of minutes by 60
• Quotient defines the number of hours.
• The remainder is number of minutes.

For example: Conversion of Seconds into Minutes:

• Divide the number of seconds by 60.
• The quotient defines the number of minutes.
• The remainder defines the number of seconds greater than full minutes.

1. 4 hrs 16 min and 6 hrs 20 min
2. 6 hrs 09 min and 7 hrs 19 min
• 2 hrs 18 min and 3 hrs 22 min

• Subtract the following:
1. 4 hrs 34 min from 6 hrs 44 min
2. 1 hrs 25 min from 4 hrs 13 min
• 3 hrs 44 min from 8 hrs 60 min
• Tell the time in the following watch: Recap

• 1 minute = 60 seconds, 1 hour = 60 minutes and 1 day = 24 hours
• 1 day = 24 hours, 1 week = 7 days and 1 year = 12 months/ 365 days
