(25°53′)*3+(107°43′)/5
=(25+53/60°)*3+(107+43/60°)/5
=(25.88333°)*3+(107.716667°)/5
=77.65°+21.54333°
=99.19333°
=99°0.19333*60′
=99°11.5988′
=93°11'36"
简便宏败解法如下:
(23+53/60)*3+(107+43/60)/5
=69+53/旁绝和20+21+(60*2+43)/300
=92+39/60+(24+8.6)/60
=92+71.6/60
=93+11/60+0.6*60/360
=93°11'36"运盯
45和60的最小公倍数是180 距链销毁离是180米 2分钟,和2分棚备30秒=2.5分斗桥的公第一道应该是60与45的最小公倍数吧180 第2道A速度设为1/2,B为1/2.5
