Understanding the Problem

Shannon is test-driving a car in Germany and reaches a speed of 95 kilometers per hour. To understand her speed in miles per hour, we need to convert the speed from kilometers per hour to miles per hour. This involves using the conversion factor between kilometers and miles.

Conversion Factor

The conversion factor between kilometers and miles is approximately 1 kilometer $\approx 0.62$ mile. This means that to convert kilometers to miles, we can multiply the number of kilometers by 0.62.

Converting Speed

To convert Shannon's speed from kilometers per hour to miles per hour, we can use the conversion factor as follows:

Speed in miles per hour = Speed in kilometers per hour $\times$ Conversion factor = 95 km/h $\times$ 0.62 mile/km = 95 $\times$ 0.62 = 58.9 miles per hour

Rounding the Answer

Since we are dealing with a speed, we can round the answer to the nearest whole number or to one decimal place, depending on the level of precision required. In this case, we can round the answer to one decimal place, which gives us a speed of approximately 58.9 miles per hour.

Conclusion

In conclusion, Shannon's speed of 95 kilometers per hour is equivalent to a speed of approximately 58.9 miles per hour. This demonstrates the importance of using conversion factors to convert between different units of measurement.

Real-World Applications

Converting speed from kilometers per hour to miles per hour has many real-world applications, such as:

Travel planning: When planning a trip from one country to another, it's essential to know the speed limits and road conditions in both countries. Converting speed from kilometers per hour to miles per hour can help travelers understand the speed limits and road conditions in their destination country.
Sports: In sports such as cycling and running, athletes often compete in events that require them to cover a certain distance in a specific time. Converting speed from kilometers per hour to miles per hour can help athletes understand their performance and set realistic goals.
Emergency services: Emergency services such as police and ambulance services often need to respond quickly to emergencies. Converting speed from kilometers per hour to miles per hour can help emergency services understand the speed at which they need to respond to emergencies.

Common Mistakes

When converting speed from kilometers per hour to miles per hour, there are several common mistakes that people make, including:

Incorrect conversion factor: Using an incorrect conversion factor can lead to incorrect results. For example, using a conversion factor of 1 kilometer $\approx 0.5$ mile instead of 1 kilometer $\approx 0.62$ mile can lead to a speed that is 12.6% lower than the actual speed.
Rounding errors: Rounding errors can also lead to incorrect results. For example, rounding a speed of 58.9 miles per hour to 58 miles per hour can lead to a speed that is 0.9% lower than the actual speed.
