First one :

 

B. All positive real numbers

 

However......if miles can only be (rounded) integer values and 0 miles is possible, then the answer might be

 

A. All whole numbers

 

 

Second one :

 

A.  All  whole numbers  (we can have 0 people waiting  or a positive integer  number of people waiting )
