1. A car travels 180 miles in 3 hours. What is the unit rate?
A. 60 mi/h B. 90 mi/h C. 183 mi/h D. 540 mi/h
1. **Problem:** A car travels $180$ miles in $3$ hours. Find the unit rate in miles per hour.
2. **Formula:** Unit rate = $\frac{\text{total distance}}{\text{total time}}$
3. **Calculation:**
$$\text{Unit rate} = \frac{180}{3}$$
4. **Simplify:**
$$\frac{\cancel{180}}{\cancel{3}} = 60$$
5. **Explanation:** Dividing $180$ miles by $3$ hours gives $60$ miles per hour, which means the car travels $60$ miles in one hour.
6. **Answer:** The unit rate is $60$ mi/h, so the correct choice is A.
