The difference in the age between Dylan and his auntie at first and in the end remains the same.
Difference in the age between Dylan and his auntie
= 5 u - 1 u
= 4 u
4 u = 48
1 u = 48 ÷ 4 = 12
The increase in age of Dylan and his auntie remains the same.
Number of years' time so Dylan's auntie will be 5 times as old as Dylan
= 12 - 2
= 10
Answer(s): 10
