Problem
QUESTION 9 Find the rate as a ratio of distance to time. Round to the nearest hundredth where appropriate. \( 120 \mathrm{mi}, 4 \) hr \( 120 \frac{\mathrm{hr}}{\mathrm{mi}} \) \( 120 \frac{\mathrm{mi}}{\mathrm{hr}} \) \( 30 \frac{\mathrm{hr}}{\mathrm{mi}} \) \( 30 \frac{\mathrm{mi}}{\mathrm{hr}} \)
Solution
Step 1 ：\( \text{Rate} = \frac{\text{Distance}}{\text{Time}} \)
Step 2 ：\( \text{Rate} = \frac{120 \mathrm{mi}}{4 \mathrm{hr}} \)
Step 3 ：\( \text{Rate} = 30 \frac{\mathrm{mi}}{\mathrm{hr}} \)
