Question

How do you convert 3 km to feet?

Answer 1

Hint: Whenever they ask to convert from one unit of distance or length to another unit, first you should be knowing the unit definition. In order to convert kilometers into feet, first convert, kilometer into miles by dividing the given kilometers by the value 1.609344 or multiply with 0.6213 and then convert the mile into feet by multiplying it with 5280.

Complete step-by-step solution:
In the above question, we have given the distance in kilometers i.e., 3 km.
Since we know that, A kilometer, is a unit of length equivalent to 1,000 meters, or about 0.6213711 approx. miles.
$\Rightarrow 1km=0.6213miles$
Now multiply both sides by 3,
$$\Rightarrow 3km=0.6213\times 3miles$$
Multiply the terms,
$$\Rightarrow 3km=1.8639miles$$
Now multiply the terms with 5280 to get the value in feet,
$$\Rightarrow 3km=1.8639\times 5280feet$$
Multiply the terms on the right side,
$$\Rightarrow 3km=9841.392feet$$

Hence, 3km is equal to 9841.392 feet approx.

Additional Information: A mile is a unit of distance equivalent to 1.60934 kilometers.
$\Rightarrow 1mile=1.60934km$
Divide both sides by 1.60934,
$\Rightarrow 1km={\displaystyle \frac{1}{1.60934}}miles$
Now multiply both sides by 3,
$\Rightarrow 3km={\displaystyle \frac{3}{1.60934}}miles$
Now multiply the terms with 5280 to get the value in feet,
$\Rightarrow 3km={\displaystyle \frac{3}{1.60934}}\times 5280feet$
Multiply the terms,
$\Rightarrow 3km={\displaystyle \frac{15840}{1.60934}}feet$
Divide numerator by denominator,
$$\Rightarrow 3km=9841.392feet$$
Hence, 3km is equal to 9841.392 feet approx.

Note: 1. A kilometer is a unit of length equivalent to 1000 meters or about 0.6213 miles. In the majority of the world, it is the most widely recognized unit for estimating the distance between places.
2.A mile is a unit of distance equivalent to 5280 feet or precisely 1.60934 kilometers. It is regularly used to quantify the distance between places in the United States and the United Kingdom.
