How do you find the longitude of a place?
Mark how much distance is between the southern parallel to your location. Add this to the latitude of the southern parallel to get the latitude of your location. To measure the longitude you must place the ruler diagonally on the west and east meridians with the ends of the 2 ½ minute ruler touching both meridians.
What is the formula to find time in simple interest?
Notes: Base formula, written as I = Prt or I = P × r × t where rate r and time t should be in the same time units such as months or years. Time conversions that are based on day count of 365 days/year have 30.4167 days/month and 91.2501 days/quarter. 360 days/year have 30 days/month and 90 days/quarter.
How do you calculate principal when given rate and time?
Principal Amount Formulas We can rearrange the interest formula, I = PRT to calculate the principal amount. The new, rearranged formula would be P = I / (RT), which is principal amount equals interest divided by interest rate times the amount of time.
How do you calculate local time from latitude and longitude?
Just divide 120 degrees by 15 degrees and you get a quotient of +8. The +8 means 8 hours after zero longitude time. Your local time is therefore 8:00 A.M of the same day to that of Greenwich. If your timezone happen to be at 120 degrees west of Greenwich, you will get a quotient of -8.
How long does it take for one degree of longitude to rotate?
One degree of longitude takes 4 minutes (1 hour = 60 minutes, divided by 15° per hour = 4 minutes per longitude). As the earth rotates from west to east, those places that lie east of Greenwich are ahead of the places that lie to the west of Greenwich.
What is the time difference between two longitudes called?
Each of these longitudes is called a degree. The 0 degree longitude passing through Greenwich, near London, is considered as standard and the time of all other time zones are calculated accordingly. The time difference between each longitude (each degree) is 4 minutes.
How to identify and calculate time zones?
To be able to identify and calculate time zones, you must know terms like lines of longitude, prime meridian and the International Date Line. What time it is at different places on earth depends on something we call lines of longitude. These are imaginary lines that run from the North Pole to the South Pole.
