3,000 seconds; or 50 minutes.
If you counted 1 number per second, it would take 63 years to count to 2 billion.
If you counted 1 number per second, it would take 3200 years to count to 100 billion.
It would take about 3.2 years.
it depends on how fast you count. If you count one number every second it would take 300,000 seconds which is 5000 minutes or 83 hours if you can stay awake that long. If you count ten numbers a second that is about 8.3 hours
The number varies (commonly, redheads have somewhat fewer hairs, while blonds have more), but the number of hairs on your head is roughly 100,000. If you count non-stop, one per second, it would take you 27.78 hours.
It would take up to 277hrs 46min 40s to count up to one million if one second is for each number
That would be Mars, Mercury being the smallest. Unless you still count Pluto, in which case Mercury would be the second smallest.
If you counted 1 number per second, it would take 63 years to count to 2 billion.
If you counted 1 number per second, it would take 3200 years to count to 100 billion.
If you counted 1 number per second, it would take 220 years to count to 7 billion.
One hour if each number takes a second. There are 3,600 seconds in one hour
It would take about 3.2 years.
If you counted 1 number per second, it would take at least 220 years to count to 6.9 billion.

It would take a million seconds = 16666.667 minutes = 277.778 hours = 11.57 days approx. This assumes (a) that you can count 1 per second which may not be realistic for large numbers and (b) that you can count for that length of time without stopping.
