Answer:
4 units
Explanation:
Since the two different locations have the same y-component (7 1/3), we need not consider y when calculating the distance between L's house and L's store.
Instead, find the distance from -1 1/3 to 2 2/3 along the x-axis.
That would be 2 2/3 - [-1 1/3], or 2 2/3 + 1 1/3, or 4 units of distance.
