A buzzer sounds every 15 minutes. If the buzzer sounded at 12:40, which of the following could be a time at which the buzzer sounded?
选项
A、4:05
B、5:30
C、6:45
D、7:15
E、8:10
答案
E
解析
一蜂鸣器每15分钟响一次,若该蜂鸣器在12:40响了,问下面哪一个可以是蜂呜器响的时间?
解:本题的正确答案是(E)。蜂鸣器12:40响后,根据题意可知该蜂鸣器只有在12:40+15n时才会再响,其中,n为整数,也即蜂鸣器可能响的时间可能是一个小时中的55分、10分、25分和40分,由此可知五个选项中只有(E)满足这一条件。
