(starting with 000000), how many km has Nano actually travelled?

Answer 1

Answer:

(3007)base9= 2194

Explanation:

Normally there are 10 digits 0,1,2,3,4,....9 which is called a base 10 system.

now the question is asking you what would the number 3008 look like in a world where there are only 9 digits (0 1 2 3 4 6 7 8 9)

Imp: The odometer shows 3008 which means it skipped 1 number (3005) so we'll actually have to convert 3007.

if the odometer reading was 3004 then we would directly converted 3004 because there is no 5 in the five numbers range [2999, 3004]

error of counting occurs every five counts so you have to look for a number with digit 5 in the five number range of

the odometer reading.

summing up:

Simply all you have to do is to convert (3007)base 10 to (3007) base 9
