Pondering

27. 1 minute of walking is 100 steps. 100 minutes is 10K Steps. 
Also about 4.5 miles is 10K Steps.
Not exact because depends on stride length and how fast but it's a great average.

5.  The step counter gives you a rough estimate

10000 steps can be quite a long distance 

Doesn't your step counter show that. Mine does.
