Question 2.
Complete the table below:
Answer:
| 120 minutes | 2 hours |
| 150 minutes | 2 \(\frac{1}{2}\) hours |
| 3 \(\frac{1}{2}\) hours | 210 minutes |
| 3 minutes | 180 seconds |
| \(\frac{1}{2}\) hours and 45 minutes | 1 hour |
| 5 hours 59 minutes and 60 seconds | 6 hours |
(i) 120 minutes = 2 hours
The remaining 30 minutes is half an hour.
So, 150 minutes = 2\(\frac{1}{2}\) hours.
(ii) 60 minutes = 1 hour
So, 180 minutes = 3 hours
The remaining 30 minutes is half an hour.
So, 210 minutes = 3 – hours.
(iii) 1 minute = 60 seconds
So, 3 minutes = 180 seconds
(iv) 1 hour = 60 minutes
So, \(\frac{1}{4}\) hours = 15 minutes
\(\frac{1}{4}\) hours and 45 minutes = 15 minutes and 45 minutes = 60 minutes = 1 hour.
(v) 60 seconds = 1 minute
So, 5 hours 59 minutes and 60 seconds = 5 hours and 60 minutes = 6 hours

| Leap Year
Usually, Earth takes 365 days and 6 hours to complete one orbit around the sun. If we think of a year as having 365 days, then there will be a change of one day every 4 years. If this goes on for a few years, the seasons will not be calculated correctly from then on. As an alternative, every four years an extra day is added to make the year 366 days long. Leap years are these kinds of years. In a leap year, February has 29 days because of the extra day. |
A leap year is a calendar year that contains an additional day compared to a common year. So, a leap year has 366 days, which is 52 weeks and 2 days.
