(a)
Nick's age =
s years
Owen's age = 6
s years
Elijah's age = (6
s - 11) years
(b)
s = 10
Difference in age remains unchanged.
Difference in age between Elijah and Nick
= (6
s - 11) -
s = 6
s -
s - 11
= 5
s - 11
= 5 x 10 - 11
= 39 years
Difference in the age when Elijah will be 4 times as old as Nick
= 4 u - 1 u
= 3 u
3 u = 39
1 u = 39 ÷ 3 = 13
Number of years' time so Elijah will be 4 times as old as Nick
