• A. 47
• B. 120
• C. 50
• D. 53

Answer: (B)

To determine how fast Karl is traveling in miles per hour when driving at 75 kilometers per hour, it's essential to convert kilometers to miles. The conversion factor between kilometers and miles is that 1 kilometer is approximately equal to 0.621371 miles.

To perform the conversion, you multiply the speed in kilometers by the conversion factor:

75 kilometers/hour * 0.621371 miles/kilometer = approximately 46.6 miles/hour.

Now, rounding this to the nearest whole number gives us about 47 miles/hour. However, if we look at the original figures provided, it appears that there was a misunderstanding regarding the correct conversion or final rounding to the answer provided. The closest answer to our calculated speed of approximately 47 miles/hour is indeed found amongst the choices.

In summary, the correct conversion gives a speed close to 47 miles/hour, which indicates that the initially selected answer may not align with the accurate calculation based on the established conversion rates. The correct understanding of this process is crucial in converting speeds and measurements accurately.
