Question

An accurate clock shows 8 o'clock in the morning. Through how may degrees will the hour hand rotate when the clock shows 2 o'clock in the afternoon?

A. 168 degrees

B. 175 degrees

C. 150 degrees

D. 180 degrees

Answer 1

(D) 180 degrees

Explanation:

There are 12 hours on the clock.

For each 1 hour, the hour hand rotates =
`360^0 / 12=30^0`

From 8 o'clock in the morning to 2 o'clock in the afternoon= 6 Hours

Therefore:

Number of degrees rotated by the hour hand =
`6 X 30^0 =180^0`
