Question

How many miles are equal to 4 kilometers?

Answer 1

Hint: Here, we will use the concept of conversion of units. Both miles and kilometers are units of length or distance and miles is a larger unit than a kilometer. We will convert the given quantity from one unit to another unit by multiplying the converting factor to it.

Formula Used:
1 mile is equal to \[1.60934\] kilometers i.e., 1 mile \[ = 1.60934\] kilometers

Complete Step by Step Solution:
We are given that 4 kilometers.
We know that 1 mile is equal to \[1.60934\] kilometers i.e., 1 mile \[ = 1.60934\] kilometers
Now, we will find the miles in the given kilometers by dividing the given kilometers by \[1.60934\] to convert into miles.
\[ \Rightarrow \] 1 mile \[ = 1.60934\] kilometers
\[ \Rightarrow \] 1 kilometer \[ = \dfrac{1}{{1.60934}}\] miles
Now, we will find the miles for 4 kilometers, so we get
\[ \Rightarrow \] 4 kilometer \[ = \dfrac{4}{{1.60934}}\] miles
\[ \Rightarrow \] 4 kilometer \[ \simeq 2.48549\] miles

Therefore, the miles in 4 kilometers is approximately \[2.48549\] miles.

Note:
We know that a mile is defined as a unit of length representing 1760 yards. It is denoted by the symbol \[mi\]. A kilometer is defined as a unit of length in the metric system which is equal to 1000 meters. It is denoted by the symbol \[km\]. Whenever the conversion is made from the smaller unit into the larger unit, then the common factor has to be divided whereas the conversion is made from the larger unit into the smaller unit, then the common factor has to be multiplied. This is common for all the conversion of SI units. These units should be remembered in finding the ratios and proportion of similar quantities. Whenever we are converting miles to kilometers or vice versa, we will get only an approximate result.
