Question

The scale on a map shows that 10 kilometers is represented by 4 centimeters. Which proportion can be used to find

the actual distance, x, represented by 20 centimeters on the map?

Answer 1

Explanation:

in my skul, we wud say dat 4 centimeters on the map is equal to 10 kilometers on actual ground

Answer 2

We can use the concept of proportion in this given problem:

10 Km/4 cm = x/20 cm

Cross multiply:
10x = 80


Solve for x:

10x/10 = 80/10

x = 8

Therefore, the actual distance on the map represented by 20 cm is 8 Km.
