Question

The graphs show the distance Traveled by two people walking at constant rates please tell me which table the unit rate that matches each graph thank you for your help

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
