-In answer to Rhea Shah's question:

In today's world, the most widely used numeral system is the decimal system with base 10. This system originated as it made it easy for humans to count using their fingers. Similarly, the origin of 60 seconds in 1 minute and 60 minutes in 1 hour goes back to the ancient Sumerians, who used a sexagesimal system that was based around the number 60. The reason for this is the popularity of the number 60. This number can be easily divided by 2, 3, 4, 5, 6 and 10. Although 100 is divisible by 2, 4 and 5, it cannot be divided by 3. A third of an hour would be 33 and some odd minutes, not giving the specific time. Hence, there are 60 minutes in 1 hour and 60 seconds in 1 minute. Also, this number aligns with geometry. There are 360 degrees in a circle and 360 equals 6 times 60. Therefore, when you divide a clock, each minute of time equates to exactly 6 degrees of the arc.
