The scale of a map says that 3 cm represents 8 km. What distance on the map (in centimeters) represents an actual distance of 20 kilometers?

What is the actual number of kilometers that is represented by 12 centimeters on the map?

PLEASE HELP ME ASAP I WILL MAKE YOU BRAINIEST!!

Step-by-step explanation:

Problem 1

Set Up the Proportion

3 cm / 8 km = x / 20 km                Cross multiply

3*20 = 8x                                        Combine the left

60 = 8x                                           Divide by 8

60/8 = x

7 4/8  = x

7 1/2 km = x

7.5 km  = x

Problem 2

3 cm / 8km = 12 cm / x                  Cross multiply

3x = 12 * 8                                      Combine the right

3x = 96                                          Divide by 3

3x/3 = 96/3

x = 32 km

51840000 cm 2
