每1小时即60分钟，分针转动360°，时针转动360/12=30°。则每分钟，分针转动360/60=6°，时针转动30/60=0.5°。以下为每个时间点的夹角计算：（1）9点整时，时针与分针夹角为90°。至9:50，分针转动6°×50=300°，时针转动0.5°×50=25°。因此，夹角为90° + 300° - 25° = 365°，或者360° - 5° = 355°。
（2）3点整时，时针与分针夹角为-90°。至3:40，分针转动6°×40=240°，时针转动0.5°×40=20°。因此，夹角为-90° + 240° - 20° = 130°，或者360° - 130° = 230°。
（3）4点整时，时针与分针夹角为-120°。至4:35，分针转动6°×35=210°，时针转动0.5°×35=17.5°。因此，夹角为-120° + 210° - 17.5° = 72.5°，或者360° - 72.5° = 287.5°。
（4）6点整时，时针与分针夹角为180°。至6:15，分针转动6°×15=90°，时针转动0.5°×15=7.5°。因此，夹角为180° + 90° - 7.5° = 262.5°，或者360° - 262.5° = 97.5°。
（5）7点整时，时针与分针夹角为150°。至7:10，分针转动6°×10=60°，时针转动0.5°×10=5°。因此，夹角为150° + 60° - 5° = 205°，或者360° - 205° = 155°。
