The second hand of a clock makes a full revolution once every minute. What is its angle of rotation after 20 seconds? After 45 seconds?

360/60 = 6

6 degrees every second

6*20 = 120 degrees


120 degrees after 20 seconds


6 * 45 = 270

270 degrees after 45 seconds


Hope I helped!

Let me know if you need anything else!
