A Correct answer
Explanation

Angle = |30H - 5.5M|. For 6:40, Angle = |30(6) - 5.5(40)| = |180 - 220| = 40 degrees.

AI explanation

Using the clock angle formula, we calculate 30 times the hours minus 11 divided by 2 times the minutes. For 6:40, this becomes 180 minus 220, giving negative 40 degrees. The absolute value of negative 40 degrees is 40 degrees.
