Time Problem

by Nisha1218 » Tue Nov 13, 2007 9:42 pm
If it is 6:27 in the evening on a certain day, what time in the morning was it exactly 2,880,717 minutes earlier? (Assume standard time in one location)

A. 6:22
B. 6:24
C. 6:27
D. 6:30
E. 6:32

HELP!!! I don't want to do long division! :(

Sorry Nisha1218! I think you have to go for a division that 2,880,717 by (24*60)! I also faced the prob and did it the way I mentioned above. Guys any other input? Waiting for that ... :wink: :cry: :oops:
Correct me If I am wrong

There are 1440 minutes in 1 day (24 * 60). So, you can immediately
see that 2,880,000 will translate to 200 days. So, eliminate that
(in mathematical terms, use the mod function)

That leaves us with 717 minutes. 12 hours translates to 12*60 = 720
minutes. So, we are 3 min shy of "just changing PM to AM"

So, 6:27 PM becomes 6:30 AM
