- <em>Since there are 24 hours in a day and 360 degrees in a circle, the sun moves across the sky at a rate of 15 degrees per hour (360° ÷ 24 hours = 15° per hour).</em>
- <em>To cover a distance of 1° (i.e., per longitude), the sun will take (60 ÷ 15 =) 4 minutes. Thus, the time difference per longitude is 4 minutes.</em>
- <em> Thus, the time difference per longitude is 4 minutes.Now, between A and B, the number of longitudes is (90 - 15 =) 75. Thus, the time to cover 75 longitudes is (75 x 4 =) 300 minutes or (300 ÷ 60 =) 5 hours.</em>
- <em> Now, since B (at 90W) is to the west of A (at 15W), time-wise, A is ahead of B, by 5 hours. So, if at A, the local time is 7 AM, the local time at B is (7 – 5 =) 2 AM.</em>

Your answer would be ONE dominant culture.
Human activities that increase the risk of natural hazards includes urbanization and agricultural development
<u>Explanation:</u>
For urbanization, more and more place is required so that houses that are built by people to settle and more roads are required for movement of people.
This leads to the cutting of trees and forests which disturbs the ecological balance resulting in natural hazards. The development of agriculture means more land is being used for agriculture purposes which means cutting down of trees again leading to natural hazards.
