Answer:
Explanation:
wow, that's tough, because of how the time is not linear. so the years vary over the measurements. Are you allowed to use a graph? if you can use excel, you can make a graph with the data and then "fit" a line to the data. Do you know how to do that? Otherwise, make a graph by hand, then fit a line to it as best you can. use A
+Bx+C. 1860 can be year zero. so you know C is 1.14 (thousand) for the above equation. then put in 1 for x at 1880 and make the A and B fit to the line, and so on. This will be really really rough. but it will work too.
