Question

How many miles are equivalent to 3.1 kilometers? 1 kilometer is about 0.62 mile

Answer 1

1.922 miles

Explanation:

Since,

1 km = 0.6

3.1 km = x

We will set up a fraction based on the given data. Let "x" be the variable.

`(0.62)/(1)=(x)/(3.1)`

Step 1: Switch sides

`(x)/(3.1)=(0.62)/(1)`

Step 2: Apply rule
`(a)/(1)=a`

`(x)/(3.1)=0.62`

Step 3: Multiply both sides by
`3.1`

`(3.1x)/(3.1)=0.62\cdot \:3.1`

Step 4: Simplify

`x=1.922`

There are 1.922 miles equivalent to 3.1 kilometers.

Answer 2

1.922 miles is equivalent to 3.1 kilometers.

Explanation:

Given:

1 km = 0.62 miles.

3.1 km = ? miles

Now, in order to find the number of miles equivalent to 3.1 km, we use unitary method with the help of the conversion factor.

From the conversion factor, we can conclude that kilometer is a smaller unit compared to that of mile.

So, conversion factor =
`(0.62\ miles)/(1\ km)`

The formula to transform 'n' kilometers to miles is given as:

`=Conversion\ factor* n`

Therefore, 3.1 km =
`(0.62\ miles)/(1\ km)* 3.1\ km`

3.1 km =
`1.922` miles

Therefore, 1.922 miles is equivalent to 3.1 kilometers.
