Okay, in this problem, we are going to try to find the actual distance between san francisco and las vegas, and they give me the model from a map, how many inches it is on the map.

So, on the map, i know that from san francisco to las vegas is 2 .1 inches, from san francisco to los angeles is 1 .3 inches, and from los angeles to las vegas is 1 inch.
00:31
I also know that the actual distance from los angeles to las vegas is 270 miles, and i am supposed to find the distance, the actual distance, from san francisco to las vegas.

So, we are going to set up a proportion.

We are going to put the map mileage on top and the actual mileage on the bottom.
