To find the age of the tortoise now, Tina can use the following equation:
\[
t = 48 + 12
\]
In this equation:
- 48 is the age of the tortoise when Tina was born.
- 12 is the number of years that have passed since Tina was born.
Now, let's calculate the tortoise's current age:
\[
t = 48 + 12 = 60
\]
Therefore, the tortoise is **60 years old** now.
\[
t = 48 + 12
\]
In this equation:
- 48 is the age of the tortoise when Tina was born.
- 12 is the number of years that have passed since Tina was born.
Now, let's calculate the tortoise's current age:
\[
t = 48 + 12 = 60
\]
Therefore, the tortoise is **60 years old** now.
