When a watch shows 7:45, the minute hand points towards East. When the watch shows 3’0 clock, which direction does the hour hand point?

A clock’s numbers and directions in the usual map are:
12 = North, 3 = East, 6 = South, 9 = West.

You’re told: at 7:45 the minute hand points East.
At 7:45 the minute hand is on 45 minutes → the 9 on the clock face. So 9 → East (given).

But normally 9 = West, so the whole compass on this clock is turned 180° (flipped). That means every usual direction is reversed:

12 (normally North) becomes South

3 (normally East) becomes West

6 (normally South) becomes North

9 (normally West) becomes East

At 3:00 the hour hand points at 3. Under this rotated map, 3 → West.

Answer: West.
