The answer would be 90 degrees because 15 minutes are between 2:00 and 1:45 and that is a quarter of an hour and so a quarter of a circle is 90 degrees
It will take her 2,000 minutes
- 9 and - 3
consider 3 units to the left and right of - 6
- 6 - 3 = - 9 ( 3 units to the left of - 6 )
- 6 + 3 = - 3 ( 3 units to the right of - 6 )
The second one they do not have to pass trough (0,0)
