Question

An accurate clock shows 8:00 in the morning. Through how may degrees will the hour hand rotate when the clock shows 2:00 in the afternoon?

Answer 1

The hour hand completes 360 degrees in 12 hours
therefore when hour hand completes one hour, it travels 360/12 degrees
= 30 degrees

From 8 am to 2 pm, the difference is 6 hours
Hence the hour hand will rotate 6 * 30 degrees
= 180 degrees

The clock hour hand will rotate 180 degrees from 8 am to 2 pm.
