#6 what is the tortoises average speed from 80 years to 160 years? show all your work on your answer document. (average speed = total distance / total time)
Answer
Explanation:
Step1: Find distance at 80 years
From the graph, at 80 years, the distance traveled is 100000 miles.
Step2: Find distance at 160 years
From the graph, at 160 years, the distance traveled is 180000 miles.
Step3: Calculate total distance
Total distance $d=180000 - 100000=80000$ miles.
Step4: Calculate total time
Total time $t = 160 - 80=80$ years.
Step5: Calculate average speed
Average speed $v=\frac{d}{t}=\frac{80000}{80}=1000$ miles per year.
Answer:
1000 miles per year
