关于时针分针的特性：
时针每分钟走0.5°,每小时走30°,分针每分钟走6°.

⑴2点半,时针从12到2.5小时走2.5×30°=75°,分针在6处,
∴夹角：180°-75°=105°.
⑵35-25=10分钟,
时针走：0.5°×10=5°,
分钟走：10×6°=60°,
⑶追及问题：
4点整,时针在分针前120°处,
设4点X分重合,
则6X=120+0.5X
11X=240
X=21又911.
即4点21又10/11分时,时针与分针重合.

已知：1天=24H 1H=60mih
24×60=144min
10H30min=630min
5h45min=345min
1440min-630=810min
1440min-345=1095min
1095min-810min=285min
285÷60=4.45
等于4小时45分钟

five forty—five
或a quarter to six
