Question

6. (a) What is the measure of the angle between two adjacent numerals on a clock dial?
(b) Through what angle does the hour hand of a clock turn in
(i) 1 hour
(ii) 20 minutes?
​

Answer 1

Answer:

1.The face of a basic analog clock is numbered from 1 to 12; the marks corresponding these numerals are called hour marks. The measurement of the angle between any two adjacent hour marks is 30

2.First note that a clock is a circle made of 360 degrees, and that each number represents an angle and the separation between them is 360/12 = 30. And at 2:00, the minute hand is on the 12 and the hour hand is on the 2. The correct answer is 2 * 30 = 60 degrees.
