Answer 1

The domain is the set of allowed values for a function.

We want the type of domain of d.

The function d is the distance she walks.

The distance can be 0.2 kilometers, 0.8 kilometers, 1.2 killometers etc. until 1.5 km [since this is the max distance].

These are real numbers. Not all are integers.
