Answer:

15

Explanation:

Kim . Scott

+5 (y+5) -5 . (y)

let's give them a random age

Kim . Scott

16 . 11

Mum Dad x3

48 . 33

48-33=15

So Kim's mum is 15 years older than Scott's dad

Answer: 15 years

Explanation:

Given : Kim is 5 years older than Scott.

Kim's mum is 3 times Kim's age.

Scott's dad is 3 times Scott's age.

Let age of Scott = y years

Then Kim's age = (y+5) years

Kim's mum age =
3* (y+5)=3y+15 years

Scott's Dad age =
3* y=3y years

Difference between Kim's mum age and Scott's Dad age = Kim's mum age - Scott's Dad age = (3y+15) - (3y) = 15

Thus Kim's mum is 15 years older than Scott's dad.
