Rotation and Revolution of the Earth

- Rotation is the movement of the Earth on its own axis

Time Calculation

- The Earth rotates 360° in 24 hours which is equal to 1 day.
- The Earth rotates from West to East on its own axis
- When calculating the time of a location, we add if a place is to the East and subtract if the place is to the West.
If the time is 7:00 a.m in Accra which is at 0°, what is the time in Nairobi which is 45° E.

1° = 4 Minutes
45° = 45 x 4 = 180 Minutes = 3 hours
Nairobi is to the East of Accra hence we add 3 hours to the time in Accra.
7.00 a.m + 3 hours = 10.00 a.m
Time in Nairobi is 10.00 a.m
