The difference in the age between Flynn and his auntie at first and in the end remains the same.
Difference in the age between Flynn and his auntie
= 5 u - 1 u
= 4 u
4 u = 28
1 u = 28 ÷ 4 = 7
The increase in age of Flynn and his auntie remains the same.
Number of years' time so Flynn's auntie will be 5 times as old as Flynn
= 7 - 2
= 5
Answer(s): 5
