Answer
Explanation:
Step1: Recall unit rate formula
Unit rate (miles per hour) is total miles divided by total hours, so formula is $\text{Unit Rate} = \frac{\text{Total Miles}}{\text{Total Hours}}$.
Step2: Substitute values
Total miles = 180, total hours = 3. So $\text{Unit Rate} = \frac{180}{3}$.
Step3: Calculate the division
$\frac{180}{3} = 60$.
Answer:
C. 60
