Question
What is the time difference between two points at 15 deg W and 75 degrees E?
Group of answer choices:
- 4 hrs
- 3 hrs
- 6 hrs
- 5 hrs
Solution
The time difference can be calculated by knowing that the Earth rotates 360 degrees in 24 hours, which means it rotates 15 degrees per hour.
The total difference in longitude between 15 degrees W and 75 degrees E is 90 degrees (75 degrees E - (-15 degrees W) = 90 degrees).
So, to find the time difference, divide the total degrees of longitude by the number of degrees Earth rotates per hour:
90 degrees / 15 degrees per hour = 6 hours.
So, the time difference between two points at 15 degrees W and 75 degrees E is 6 hours.
