Answer: Kim is 48. Kim's sister is 12.


Explanation:

Let Kim represent 4x and her sister represent x.

4x+x=60

Place 1 by x. (That's just a math rule)

4x+ 1x =60

5x=60

x=60/5

x=12

This is Kim's sister age. To find Kim's age all we have to do is multiply 12 and 4.

12×4= 48. Kim's age. Hope this helped.
