(d) starts at 5 and makes 3/4 of a revolution, clockwise?
Solution:
(a) At 6
(b) At 8
(c) At 8
(d) At 2

Question 3.

Solution:
(a) West
(b) West
(c) North
(d) South
No, it is not necessary to specify because whether we turn clock wise or anti-clockwise, one full revolution will bring use back to the original position.
