Answer 1

Answer:

Vince began practicing piano at 11:15 P.M

He stopped at 11:35 P.M

=> He practiced in 35 - 15 = 20 mins = 1/3 hour.

=> 1/3 hour means 1/3 circle, the number of degrees the minute hand turned:

N = (1/3) x 360 = 120 deg (1 circle = 360 deg)

Hope this helps!

Answer 2

*Answer*
120 degrees

*Explanation*
A clock is a circle and therefor has 360 degrees. To find how many degrees are in a five minute time span, divide 360 by 12 (the amount of five minute “chunks”)

360/12 = 30

Between 11:15 and 11:35, 20 minutes pass. 20/5 = 4, which means there are 4 five minute intervals. Multiply that by 30, the amount of degrees in every five minute “chunk”

4 x 30 = 120

That means the hand moved 120 degrees.

Hope I could help.
