Question

What is the angle between the hour’s hand and minute’s hand of a clock at (i) 1.40 hours, (ii) 2.15 hours? (Use 1° = 60 minutes).

Answer 1

(i)

From the figure, the angle made by the hour and minute hands at 1.40 hours is given by:

240° − (30° + 20°) = 240° − 50° = 190°

(ii)

Here,

∴Angle between them = 90° − (7.5° + 60°) = 22.5°
