Hands of a clock suggest an angle whose measure is continually changing. how many degrees does a minute hand move through during each time interval?
9 min
35 min
45 min
explain i need !

A clock has sixty minutes for every one rotation. One full rotation has 360°. Knowing this, we can set up a ratio:

So, for every 1 minute, a clock hand moves 6°.

Next, all we have to do is multiply the number of minutes by 6°:


So:
In 9 minutes, a clock-hand moves 54°
In 35 minutes, a clock-hand moves 210°
In 45 minutes, a clock-hand moves 270°

Hope this helps!
