age difference = 8 yrs

no. of yrs later: u

3+u = (48-8)/2 = 20
u = 17

See 2 Answers

11+3= 14
48-14= 34
34/2 = 17.
Hence, 17 years time their total age be 48 years old.

Thank you
Let n be the number of years Megan and her brother take to reach 48 years old.

Megan's age in n years = 11+n
Her brother's age in n years = 3+n

Total age in n years = 48
11 + n + 3 + n = 48
14 + 2n = 48
2n = 48 - 14 = 34
n = 34/2 = 17

Number of years = 17
