Answer 1

It rotates 180° to move from 10 to 4 on a clock

Answer 2

Answer:

180 °

Step-by-step explanation:

Given : An accurate clock shows 10 o'clock in the morning

To Find : through how may degrees will the hour hand rotate when the clock shows 4 o'clock in the afternoon?

Solution :

Hours between 10 am to 4 pm = 6 hours

Since hour hand completes 360 degrees in 12 hours

So, it rotates in 1 hour = $\frac{360}{12}$

So, it rotates in 6 hour = $\frac{360}{12}\times 6$

                                      = $180^{\circ}$

Hence hour hand will rotate 180 ° when the clock shows 4 o'clock in the afternoon
