What is the angle between the hands of a clock at 5:10 ?

Answer: B

Correct answer: 95°

Measure both hands from the 12 o’clock mark.

\[\text{Hour hand} = 5 \times 30 + 10 \times 0.5 = 150 + 5 = 155°\]

\[\text{Minute hand} = 10 \times 6 = 60°\]

\[\text{Angle} = 155 - 60 = 95°\]

Answering \(90°\) ignores the \(5°\) the hour hand has moved past the 5.
