Answer:

A. 3 ≤ y ≤ 5

Step-by-step explanation:

The range is the set of values that the variable y can take. In this case, the variable y is the speed, so the range is the set of values of Rosalie's speed in her training.

Since the speed takes values from 3 miles per hour to 5 miles per hour, the range is

3 ≤ y ≤ 5
