It is currently 7:16 PM. At what time in the morning was it exactly 19,443 minutes earlier?
Choose the correct answer.
A) 7:11 B) 7:13 C) 7:17 D) 7:19 E) 7:21
Converting 19,443 minutes to hours, we get 19,443/60 = 324 R 3; that is 324 hours and 3 minutes. All of the answers are during the same hour of the morning, thus the hours can be assumed to bring us into the 7 AM hour evenly from 7:16 PM. Thus 324 hours ago was 7:16 AM. Take an extra 3 minutes off, and it was 7:13 AM. 7:13
