To find the number of inches per foot, we can start from the relationship you've given:
There are \( 48 \) inches in \( 4 \) feet.
To find the number of inches in \( 1 \) foot, we can divide the total number of inches by the number of feet:
\[ \text{Inches per foot} = \frac{48 \text{ inches}}{4 \text{ feet}} = 12 \text{ inches per foot} \]
Thus, there are 12 inches per foot.
