Answer:
[tex]\frac{19}{12}[/tex] feet
Step-by-step explanation:
First, we need to find the height after one year:
2.25 + 1 1/6 = [tex]\frac{41}{12}[/tex]
Now to find the amount in the second year, we can subtract the above amount from 5:
5 - [tex]\frac{41}{12}[/tex] = [tex]\frac{19}{12}[/tex]
So in the second year it grew [tex]\frac{19}{12}[/tex] feet
