From 12 noon to 4.24 pm, time elapsed = 4h 24 min
in 12 hours, hour hand completed = 360°
in 1 hour, it completes = 360/12 = 30°
in 4 hours, it completes = 30×4 = 120°
in 24 minutes, it completes = 24/60 × 30 = 12°
total angle in 4h 24 min = 120+12 = 132°
Thus, the hour’s hand would have moved 132° from 12 noon to 4.24 p.m.
