Question

Use the table to answer the question.The Diaz family went on a road trip for vacation. The table includes a cumulative chart of the time they traveled compared to the distance they drove.Over which interval was their average speed the fastest: [0,4], [4,7], [7,9], or [9,12]?Explain your reasoning in 1–2 sentences.

Answer 1

I don't see the table — please paste the distances at times 0, 4, 7, 9, and 12. To solve it yourself: compute average speed on each interval as (change in distance)/(change in time); the interval with the largest quotient is the fastest.
