Answer 1

There are multiple interpretations to this question. One scenario that I can think of is that the question asks to prove 'unit' distance between one black dot and one white dot. Note the term 'one unit'.

Now a unit is not defined as such. You can define a metre, a centimetre, etc. But a unit can be anything. It may be equal to one fermi-metre, or 56 nanometres. It is up to you. So basically, you only need to say that as long as the dots are uniformly distributed, the distance between one white dot and one black dot is 'one unit'.
