Question is in the pictures

Answer 1

360 /12 = 30

Each 5 minutes is 30 degrees

2*pi/12 = pi/6

each 5 minutes is pi/6 degrees

pi/3 = 2*pi/6 = 2 * pi/6  = 2* 5 minute = 10 minutes  

 the minute hand moves from 4 to 6

2 * pi/3 = 2 * (2*pi/6) = 4 *(pi/6) = 4 * 5 minutes = 20 minutes

The minute hand moves from 3 to 7

5 * pi/6 = 5 * 5 minutes = 25 minutes

the minute hand moves from 5 to 10

7 * pi/6 = 7 * 5 minutes = 35 minutes

the minute hand moves from 2 to 9
