If a clock face reads 1 o’clock, how many hours must Pass the hands to form a straight angle

The hour hand moves at a rate of 30 degrees per hour. Therefore, to form a straight angle from 1 o'clock (which is at 30 degrees), the hour hand must move 180 degrees.

180 degrees divided by 30 degrees per hour is 6 hours. So, the hands of the clock must pass 6 hours for them to form a straight angle.
