Question

how far is it from the restaurant to the post office?
(there is a coordinate plane with various icons representing different locations: hamburger joint, post office, restaurant, bakery, magic shop, hardware store, office supply store. a legend on the right identifies each icon. the question is to find the distance between the restaurant and the post office, with a box to fill in the number of units.)

Explanation:

Step1: Find coordinates of points

Restaurant is at \((3, 1)\), post office at \((1, 1)\).

Step2: Calculate horizontal distance

Since \(y\)-coordinates are equal, distance is \(|3 - 1| = 2\).
