Other Measures of Time:
To measure long period of time we use dates, weeks, months and years.
1 year = = 12 months or 365/366 days 1 month = 30/31 days or 4 weeks approx. 1 week = 7 days |
1 hour = 60 minutes 60 seconds = 1 minute |
Keep in Mind
Only February has 28 days. In leap years, it has 29 day
1. Change 7 hours 20 minutes into minutes:
1 hour 60 minutes
Therefore, 7 hour = 7 × 60 minutes = 420 minutes
Now, 7 hours 20 minutes
= 420 minutes + 20 minutes
= 440 minutes
2. Change 6 days into hours:
1 day = 24 hours
Therefore, 6 days 6 × 24 hours
= 144 hours
3. Change 5 months 2 weeks into days:
1 month 30 days.
Therefore, 5 months = 5 × 30 = 150 days
1 week = 7 days
Therefore, 2 weeks = 2 × 7 = 14 days
Now, 5 months 2 weeks
= 150 days + 14 days
= 165 days
4. Change 4 minutes 30 seconds into seconds.
1 minute 60 seconds
Therefore, 4 minutes = 4 × 60
= 240 seconds
Now, 4 minutes 30 seconds
= 240 seconds + 30 seconds
= 270 seconds
