Question

The scale on map is 2 cm =25 miles dave measured the distance to the next town at 5 cm

Answer 1

Proportion states that the two ratios or fractions are equal

Given the statement:

The scale on map is 2 cm =25 miles.

Dave measured the distance to the next town at 5 cm.

We have to find the what miles away is the next town.

Let x be the distance in miles away is the next town.

By definition of proportion:

`(2)/(25) = (5)/(x)`

By cross multiply we get;

`2x = 5 * 25`

Simplify:

`2x = 125`

Divide both sides by 2 we get;

x = 6.25 miles

Therefore, 6.25 miles away is the next town.
