Question

The graphs show the distances traveled by two people walking at constant rates. Drag to the table the unit rate that matches each graph.

Answer 1

from left: 220, 177

Explanation:

unit rate = first derivative = slope

first graph;

slope = (880-660)/(4-3) = 220 ft/min

2nd graph;

slope = (177-0)/(1-0) = 177 ft/min
