Question

The actual distance between Point A and Point B is 200 meters. A length of 1.9 feet represents this distance on a certain wall map. Point C and Point D are 3.8 feet apart on this map. What is the actual distance between Point C and Point D?

Answer 1

Answer:

So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by  

2.5/1 .    Then, 20 x 2.5=50. So the answer is 50 km<-------------- Final answer

Hope this helps,

Answer 2

Answer:

400m

Step-by-step explanation:

Let  be the actual distance between point C and D

Using ratio method,

1.9 : 200

3.8 : x

Now,

1.9/200= 3.8/x

x=400

Actual distance between point C and D is 400m
