Brooke is 8 years old! This is what I did⬇️
5x2=10. (In 5 yrs 10 will add to the sum of their age.
29-10=19. (The sum of their ages right now is 19)
11 + 8 = 19 ( 11 is 3 more than 8 and it equals their ages together)
Brooke:8
Samantha:11
I am not sure but I would say either step 2 or 4 but I am not 100% sure I hope you do well. Good Luck:)
The answer would be 8746 ft :)
