Question

the hand of the clock below is pointing at the 3. suppose that the hand moves clockwise until it points at the 8. how many degrees does the hand move? your answer

Explanation:

Step1: Calculate degrees per hour - mark

A full - circle of a clock is 360°. There are 12 hour - marks on a clock. So the angle between each hour - mark is $\frac{360}{12}=30^{\circ}$.

Step2: Calculate number of hour - marks passed

The hand moves from 3 to 8. The number of hour - marks passed is $8 - 3=5$.

Step3: Calculate total degrees moved

Since each hour - mark is 30°, the total degrees moved is $30\times5 = 150^{\circ}$.

Answer:

150
