What is the range of this relation?

A.
0 ≤ y ≤ 5
B.
y ≤ 5
C.
y ≥ 0
D.
3 ≤ y ≤ 5

Rosalie is training for a marathon. She jogs for 30 minutes at a rate of 5 miles per hour, then she decreases her speed over a period of time and walks for 60 minutes at a rate of 3 miles per hour.

Therefore, the speed (y) of Rosalie ranges from 5 mph to 3 mph including the values.

So, the range of this relation is 3 ≤ y ≤ 5. (Answer)
