How many miles are equal to 1.7 km (1 inch = 2.54 cm)
How many miles are equal to 1.7 km (1 inch = 2.54 cm)
The Correct Answer and Explanation is:
Conversion of 1.7 km to miles (Given: 1 inch = 2.54 cm)
To convert 1.7 kilometers to miles, we’ll use the standard conversion factor between kilometers and miles:
- 1 mile = 1.60934 kilometers
So:Miles=1.7 km1.60934≈1.056 miles\text{Miles} = \frac{1.7 \, \text{km}}{1.60934} \approx 1.056 \, \text{miles}Miles=1.609341.7km≈1.056miles
✅ Answer: 1.7 kilometers is approximately 1.056 miles
Explanation
To understand how many miles are equivalent to 1.7 kilometers, we first need to understand the relationship between different units of length. A kilometer is a metric unit, commonly used in most countries around the world, whereas a mile is part of the imperial system, primarily used in the United States and the United Kingdom.
The key to converting between these units lies in using the correct conversion factor. It is widely accepted that:
- 1 mile equals 1.60934 kilometers, and therefore,
- 1 kilometer equals approximately 0.621371 miles
Using either of these relationships allows for accurate conversion. In this case, we are converting 1.7 kilometers to miles, so we divide 1.7 by 1.60934:1.7÷1.60934≈1.056miles1.7 \div 1.60934 \approx 1.056 miles1.7÷1.60934≈1.056miles
Now, you might wonder why the given information includes “1 inch = 2.54 cm.” This is another standard conversion, often used when converting between metric and imperial systems. However, it’s not directly necessary in this case because we already have the kilometer-to-mile conversion ratio. The inch-to-centimeter information becomes useful if we were converting from smaller units (like cm or inches) to kilometers or miles indirectly.
In summary, by understanding the fixed relationship between kilometers and miles (1 mile ≈ 1.60934 km), and applying basic division, we can determine that 1.7 km is about 1.056 miles. This type of conversion is especially useful in navigation, travel, and international communication.
