If a clock started at noon, then the angle traversed by the hour hand at 5.45 Pm will be:
- 112.50
- 1200
- 172.50
- None of these
Answer: (4) 172.5o
Explanation:-
Angle traced by hour hand in 12 hrs = 360o
Therefore, angle traced by hour hand in 5 hours 45 minutes = 23/4 hrs
= 360 x 23 / 12 x 4
= 30 x 23/4
= 15 x 23/2
= 345/2
= 172.5o
Then, the angle traversed by hour hand at 5.45 PM will be 172.5o.
Hence, the answer is (4) 172.5o.
