Answer 1

Given: a 12-hour clock when the time is 9 ∶ 25.

Formula used:

\(\text{Angle between the minute hand and the hour hand}={(60 \:H - 11\:M)\over 2}\)

where H represents hour and M represents minutes.

Calculation:

\(\text{Angle between the minute hand and the hour hand}={(60 \times9\: - \:11\times25)\over 2}\)

\(\text{Angle between the minute hand and the hour hand}={265\over 2} = 132.5^\circ\)

Thus, the approximate angle between the minute hand and the hour hand is ' \(\textbf{130}^\circ\: \)'.
