The hour hand of a clock is 7 cm long. The angle swept by it between 7:00 a.m. and 8:10 a.m. is:
A. $\left(\frac{35}{4}\right)°$
B. $\left(\frac{35}{2}\right)°$
C. 35°
D. 70°
✅ Answer & Solution
✅ Correct Answer: C
The hour hand completes 360° in 12 hours = 720 minutes, i.e. it sweeps $0.5°$ per minute. Time elapsed from 7:00 a.m. to 8:10 a.m. = 70 minutes. Angle swept $= 70 \times 0.5° = 35°$.
