Lauren and Maria are delivering donated clothing to homeless shelters in their area. They make their first delivery and then consult a map before proceeding to the next.

1. A ratio expresses the number of times one number contains another.  The distance between the two shelters is real-life 45 km.

### What is a Ratio?

A ratio expresses the number of times one number contains another. For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
Given that 1 centimeter on the map is equal to 3 kilometers in real. Therefore, the ratio can be written as,
Distance on map/Distance in real =  1 centimeter/3 km
Also, it is given that the distance between the two shelters is 15 centimeters on the map. Therefore, the distance between the next shelter is,
15 centimeter/Distance in real =  1 centimeter/3 km
Distance in real = (15 centimeter × 3km) / 1 centimeter
= 45 km
Hence, the distance between the two shelters is real-life 45 km.
