Question

PLEASE HELP!

A map uses a scale where 1 inch = 3 miles. The actual distance between City A and City B is 231 miles. What is the distance between the cities on the map?

I got 693, but I am not sure I really understand the question.

Answer 1

Answer: 77 inches.

Explanation:

You know that this map uses this scale:

`1in=3mi`

This means that 1 inch in the map represents 3 miles.

In this case, you know that the actual distance between City A and City B is 231 miles, then, to find the distance between the cities on the map, you can set up de following proportion:

`(1in)/(3mi)=(x)/(231mi)`

Now, you need to solve for "x":

`(231mi)((1in)/(3mi))=x\\\\x=77in`

Answer 2

77 inches

Explanation:

Given

1 inch = 3 miles in map

We are also given the actual distance between City A and City B = 231 miles.

In order to get the distance in inches = Distance between City A and City B in miles/ 3

We are dividing the distance by 3 to get the distance in inches.

So,

Distance on map = 231/3

= 77 inches
