Answer:In the case of an arc, one degree has been divided into 60 minutes while each minute is broken down into 60 seconds. This usage of seconds, minutes and degrees is called DMS notation.
All of us know that one day includes 24 hours while one minute consists of 60 seconds. As we notice the clock-arm movement, it performs two complete rotations each day to mark 24 hours of the day. The hour arm makes two circles, i.e., 360 degrees arc each in one day.
Calculation: 360 x 2 = 720 degrees
A clock is built with 12 partitions. So, for a single partition, we witness: 1 degree = 720/ 12 = 60 minutes
Therefore the highlighted statement is proved.
