Question

A clock is started at 5 pm. through how many degrees will the hour hand rotate when the clock shows quarter past 9?

Answer 1

Hour hand advances 30deg per hour. 

It traverses 4 hours. So, total degrees would be 120 at 9 o’clock

. We assume we are measuring rotation for 9.15 pm.

For another quarter hour,

degrees would be = 30/4 = 7.5

Therefore, the total would be 127.5 degrees.
