Step 2:: Understand the Conversion
To convert kilometers per hour (km/h) to miles per hour (mph), we need to know the conversion factor between kilometers and miles.
Step 3:: Recall the Conversion Factor
1 \text{ mile} = 1.60934 \text{ kilometers}
Step 4:: Set Up the Conversion Calculation
We want to convert $$40 \frac{\text{kilometers}}{\text{hour}}$$ to miles per hour.
Step 5:: Perform the Calculation
40 \text{ km/h} \times \frac{1 \text{ mile}}{1.60934 \text{ km}} = \frac{40}{1.60934} \text{ miles/h}
Step 6:: Calculate the Result
\frac{40}{1.60934} \approx 24.86 \text{ mph}
Step 7:: Round to the Nearest Whole Number
24.86 \text{ mph} \approx 25 \text{ mph}
Final Answer
The correct answer is B. 40 kilometers per hour is equivalent to approximately 25 miles per hour.
