Step 1:I'll solve this problem step by step, converting miles per hour to kilometers per hour.
Step 2:: Understand the given conversion
We know that 2 miles = 3 kilometers
Step 3:: Set up the conversion ratio
\frac{2 \text{ miles}}{3 \text{ km}} = \frac{1 \text{ mile}}{1.5 \text{ km}}
Step 4:: Convert 80 miles per hour to kilometers per hour
80 \text{ miles/hour} \times \frac{1.5 \text{ km}}{1 \text{ mile}} = 120 \text{ km/hour}
Step 5:: Verify the calculation
- Multiply 80 by 1.5 - 80 × 1.5 = 120
Final Answer
The correct answer is D. 120. Explanation: - We used the given conversion of 2 miles = 3 km - Simplified this to 1 mile = 1.5 km - Multiplied 80 miles/hour by 1.5 km/mile - This directly converts the speed to kilometers per hour
