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

Anton [14]

Answer:

1.922 miles is equivalent to 3.1 kilometers.

Step-by-step 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 = $\frac{0.62\ miles}{1\ km}$

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

$=Conversion\ factor\times n$

Therefore, 3.1 km = $\frac{0.62\ miles}{1\ km}\times 3.1\ km$

3.1 km = $1.922$ miles

Therefore, 1.922 miles is equivalent to 3.1 kilometers.

Mrs.Smith has two similiar recycling bins in her office. The dimension of the smaller bin can be found by dilating the dimension

nikklg [1K]

Answer:

The dimension of the larger bin is x and the smaller bin is $0.75x$ .

Step-by-step explanation:

Let the dimension of the larger bin is x.

It is given that the dimension of the smaller bin can be found by dilating the dimension of the larger bin by a scale factor of 0.75

In order to find the dimension of the smaller bin multiply the dimension of the larger bin by 0.75

$(x)(0.75)=0.75x$

Hence, the dimension of the larger bin is x and the smaller bin is $0.75x$ .
