hour hand moves 0.5 degrees in 1 second and minute hand moves 6

degrees in 1 second.There are 12 digits and eachof them is 30 degrees.

In 1 minute minute hand moves 6 degrees.Hour hand is 1/12 of minute

hand and it is 0.5.

The angle between hour hand and minute hand increases 5.5 degrees in 1

minute. This is how I got it:6-0.5 is 5.5 degrees.
