Counting Numbers
One day, my maths teacher asked everybody to find out how much time it will take to count to a billion, if one number is counted per second, twenty-four hours per day.

i hope i did it right...
ignoring leap years
31.709791983764586504312531709792 years
one billion seconds
actually its 31.709791983764586504312531709792 days not years
It takes exactly 11574 days and 6400 seconds( One Hour 46 mins and 40 seconds)
It is 31 years, 259 days, 1 hour, 46 minutes, and 40 seconds roughly, not considering leap years. Since leap years happen every 4 years, you could use 365.25 (still not exact but closer), but then you need to consider when did you start counting? Leap years only happen every four years, but they do not happen every 100 years, but do happen every 400 years. This means that year 1900 will not have a Feb. 29, but year 2000 will. It will be 1,000,000,000 seconds and the answer will be years, not days (as some genius pointed out). Reversing the answer to calculate if it gives you 1,000,000,000 exactly is the true test.
My answer: It is 31 years, 259 days, 1 hour, 46 minutes, and 40 seconds with no leap years. Depending on how may leap years occurred in these almost 32 years (could have been 6, 7, or 8 leap years depending on what year you started counting) the 259 days could be 251, 252, or 253. So there is really no correct answer for this question.
1 billion second
or
16666666.67 mins
or
277777.78 hrs
or
11574.074* days
or
31.709791983764586504312531709792 years
*repeats
O<-< stick man
did not copy
o<-<
1 second, it never says you have to start from 1.......
Never!
"if one number is counted per second..."
That means repeating the same number over and over and over and over and over and...
well with the logic of Patrick A., i think he would be right
1000000000/60=16666666.67min
ans/60=277777.7778hours
ans/24=11574.07407days
ans/365.25=31.68808781years
true years
