What year would it be 1 billion minutes ago?
Oh, dude, let me grab my calculator real quick... okay, so 1 billion minutes is about 1,901 years. So, if we go back that many years from now, we'd be chilling around the year 120 AD. Like, can you imagine what the memes were like back then?
How many years ago is 1 billion seconds ago?
There are 60 seconds in a minute and sixty minutes in an hour, so each hour is 3600 seconds. Multiply 24 to get days, and then 365.25 to get years, accounting for leap years. This is 31,557,600 seconds per year. Divide 1,000,000,000 seconds by 31,557,600 seconds per year, and you get 31 years, 251 days, 7 hours, 46 minutes and 40 seconds. (Why didn't I figure out the months? Because the months aren't equal!)
Exactly how many minutes is it before 8o'clock if 40 minutes ago it was 3x as many minutes past 4 o'clock?
40x3=120minso... divide 120 into 60 gets you 2so... 2hrs + 40minso.. 120+40=160 minutes[not sure. ask math teacher. LOL)
How many years ago is 2.8 Gyr?
1 Gyr is 1 billion years, so 2.8 Gyr is 2.8 billion years ago.
If 12'o clock midnight equals 4.6 billion years ago and 1 hour equals 1 billion years how many years is 3 hours and 6 hours?
3 hours = 3 hours PAST 12 o'clock = (3 x 1 billion) - 4.6 billion = 3 billion - 4.6 billion = -1.6 billion years = 1.6 billion years ago6 hours = 6 hours PAST 12 o'clock = -1.6 billion years + (3 x 1 billion) = -1.6 billion + 3 billion = 1.4 billion years ago
