How long would it take to count to one million with the rule that you can say 5 digits per second and numbers are read out in digits rather than names eg thousand would become one zero zero zero?

Answer 1

Assuming that you start with the number "0", I wrote this formula:

(9-0+1)*1+(99-10+1)*2+(999-100+1)*3+(9999-1000+1)*4+(99999-10000+1)*5+(999999-100000+1)*6+7

This formula calculates how many total digits there are.

Then once I have the number of digits = 5888897 digits, I divide by 5 because you say 5 per seconds.

5888897 / 5 = 1177779.4 seconds

Now using Google to convert seconds to minutes or hours or days:

1 177 779.4 seconds = 19 629.6567 minutes

1 177 779.4 seconds = 327.160944 hours

1 177 779.4 seconds = 13.631706 days
