What is the smaller angle between the hour hand and the minute hand of a clock at 6:45?
A. 72.5°
B. 90°
C. 67.5°✓ Correct Answer
D. 292.5°
💡 Solution & Explanation
Use angle = |30 × H − 5.5 × M|. Here |30 × 6 − 5.5 × 45| = |180 − 247.5| = 67.5°. The 5.5 accounts for the hour hand moving half a degree every minute.
