According to the table you provided, after 12 seconds, the object has traveled 54 inches.
To convert inches to feet, you can use the conversion factor that 12 inches equals 1 foot.
So, to find out how far the object travels in feet after 12 seconds, you can calculate:
\[ \text{Feet} = \frac{\text{Inches}}{12} = \frac{54}{12} = 4.5 \text{ feet} \]
Therefore, after 12 seconds, the object will travel 4.5 feet.
