Why ,there are difference of 4 minutes between two degrees?
Answers
Answer:
because there is the distance which can be covered in 4 min between 2 degree
The 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).
