Question

What is the angle of rotation of the minute hand of a clock moving from 6:10 to 7:00?

A.
–300°
B.
–60°
C.
60°
D.
300°

Answer 1

The minutes hand goes from 10 minutes to 60 minutes.
That is the same as the minutes hand going from 2 o'clock to 12 o'clock.

Answer 2

From 3 o'clock to 6 o'clock, from 6 o'clock to 9 o'clock, and from 9 o'clock to 12 o'clock, each of these intervals makes a right angle, so each one is 90 degrees.

From 12 o'clock to 3 o'clock it's also a 90 degree angle.
That means each hour is 90/3 = 30 degrees.

From 2 o'clock to 3 o'clock it's 30 degrees.
From 3 o'clock to 12 o'clock it's 3 * 90 degrees.

Add the two degree measures above to find your answer.
