In one Minute of time, how does the earth rotate in minutes or seconds of longitude?

rotation=360 degrees/ number minutes in the day.

360/1440 = 0.25 is that the right answer

Yes, that is correct. In one day, the Earth completes a full rotation of 360 degrees. Since there are 24 hours in a day and 60 minutes in an hour, there are 24*60 = 1440 minutes in a day. To find out how much the Earth rotates in one minute of time, you divide 360 degrees by 1440 minutes, which equals approximately 0.25 degrees per minute. Therefore, the Earth rotates about 0.25 degrees of longitude in one minute.
