Find the angle traced by the hour hand of a correct clock between 10 a.m. and 3:44 p.m. on the same day.

Solution

✅ Correct Option: 3

From 10 a.m. to 3:44 p.m.:

10 a.m. to 3 p.m. = 5 hours

3 p.m. to 3:44 p.m. = 44 minutes

Total time elapsed = 5 hours 44 minutes


The hour hand completes one full circle (360°) in 12 hours.

In 1 hour, the hour hand moves:

360°12=30°\frac{360°}{12} = 30°

In 1 minute, the hour hand moves:

30°60=0.5°\frac{30°}{60} = 0.5°


Angle traced in 5 hours:

5×30°=150°5 \times 30° = 150°


Angle traced in 44 minutes:

44×0.5°=22°44 \times 0.5° = 22°


Total angle traced:

150°+22°150° + 22°

=172°= 172°

Therefore, the angle traced by the hour hand is 172°.
