100 minutes.

How many minutes before midnight is it if one hour ago it was five times as many minutes past 9 p.m.?
意思是午夜前的某个时刻，它和午夜之间的分钟数是1小时之前的时刻与晚上9点之间的分钟数的5倍。

晚9点到午夜是180分钟，减掉中间的1小时，剩下120分钟，也就是说午夜之间的分钟数与晚上9点之后的分钟数之和是120，而前者是后者的5倍，所以前者是100分钟，后者是20分钟。

20minutes
by the way,do you understand Chinese?
意思是：现在离午夜12点还有多少分钟，知道的已知条件是现在这个时间的一个小时前到晚上9点的时间，是现在离12点时间的五倍。
列方程：设现在离12点还有x分钟，9点到12点一共180分钟，即x+60+5x=180,解得x=20分钟
english vision: if there is x minutes before midnight(12p.m)
there are 180 mins between 9 and 12p.m,
from the question we can catch :5x+60+x=180,x=20mins

If that time is X a.m.

X=5X-21(9 p.m.=21)

X=5.25 hours=315mins.

315 minutes before midnight .

有智商测试,如果你足够聪明,帮助我解决它,谢谢!!!多少分钟在午夜是它之前如果一个小时前是五时间许多分钟通过9 p 。m.?如果您知道怎么对做它,请帮助我翻译它,谢谢!!!!!!!
