Answer 1

Answer:

15

Step-by-step 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 2

Answer: 15 years

Step-by-step 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 = $3\times (y+5)=3y+15$ years

Scott's Dad age = $3\times y=3y$ 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.
