What is the angle covered by the hour hand in 1 hour 20 minutes?

The correct answer is Option (2) → 40°

The hour hand moves 360° in 12 hours.

$\text{Angle per hour} = \frac{360°}{12} = 30° \text{ per hour}$

Step 1: Convert time to hours

$1 \text{ hour } 20 \text{ min} = 1 + \frac{20}{60} = 1 + \frac{1}{3} = \frac{4}{3} \text{ hours}$

Step 2: Angle covered

$\text{Angle} = 30° \times \frac{4}{3} = 40°$
