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

Answer:

The actual distance is 127 miles.

Step-by-step 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:

$\frac{6.35}{x} =\frac{1}{20}$

By using cross multiplication we get:

⇒  $127=x$

⇒  $x=127\ miles.$

Therefore, the actual distance is 127 miles.
