Question

On a map, the distance from Los Angeles to San Diego is 6.35 cm. the scale is 1cm = 20 miles. What is the actual distance?

Answer 1

The actual distance is 127 miles.

Explanation:

Given:

On a map, the distance from Los Angeles to San Diego is 6.35 cm.

The scale is 1 cm = 20 miles.

Now, to find the actual distance.

Let the actual distance be
`x\ miles.`

And the distance on map is 6.35 cm.

So, 6.35 cm is equivalent to
`x\ miles.`

And as given on the scale 1 cm is equivalent to 20 miles.

Now, to get the actual distance by using cross multiplication method:

`(6.35)/(x) =(1)/(20)`

By using cross multiplication we get:

⇒
`127=x`

⇒
`x=127\ miles.`

Therefore, the actual distance is 127 miles.
