Why is the time difference between each meridian of longitude 4 minutes? Explain.
Answers
Answer:
The earth has 360 imaginary lines called longitude or meridians running vertically between the poles. Each of this are called the degree. So the time difference between each longitude in 4 mins.

Explanation:
Earth rotates once a day, so that’s 360 degrees (the number of degrees in a circle) in 24 hours. If you do the math, that’s 360/24 = 15 degrees per hour. Each time zone is of course one hour, so there are 24 time zones of 15 degrees each.
The question is asking about minutes instead of hours, so we need to think of each time zone as having 15 degrees in 60 minutes. To solve for 1 degree, we divide 60 minutes by 15 degrees, so 60/15 = 4. In other words, it takes 4 minutes for each degree of the Earth’s surface to rotate past a fixed point in space.
The Earth is 24,901 miles around the equator, so each degree is 69.1 miles across along the equator. And to take it one step further, the Earth is spinning at a rate of 1037 miles per hour along the equator (24,901 miles in 24 hours).The
