Question

The ratio of centimeters on a map to distance in kilometers is 2 to 5.

If two cities are 16 cm apart on the map, what is the actual distance in kilometers between the two cities? You can use a double number line diagram to help you solve.

Answer 1

Answer: 40 kilometers

Step-by-step explanation: Since the word ratio is cm/km (centimeter/kilometer), and the number ratio is 2/5, you will have to create another set and put the 16 cm next to the 2 cm. So it would be 2/5=16/X. Now you have to find the value of x. First, you have to multiply 5 by 16, which is equal to 80. Now you divide it by 2 and you will get 40 kilometers as your final answer.
