#1 The graph illustrates a continuous increase in the delivery truck's distance over time, implying a smooth and consistent ride. #2 The average rate of change from 1.5 to 2 hours indicates the truck's speed, representing the distance covered per hour in this time interval.
#1 The graph indicates a steady increase in the distance traveled by the delivery truck over time. As time progresses, the distance covered by the truck consistently rises, implying a continuous and smooth ride.
#2 The average rate of change from 1.5 hours to 2 hours is calculated by finding the slope of the line connecting the two points on the graph. Using the formula (change in distance)/(change in time), the average rate of change represents the truck's speed during this time interval, indicating the distance covered per hour.
