Question

A coastline is lost to erosion at a constant rate. The graph shows the amount of coastline lost overtime . How many years will it take to lose 48 feet of the coastline

Answer 1

48 years falls between 40 to 50 on the graph

If you trace from a point close to 50 on the y -axis to meet the slope line

the point of intersection between the trace and the slope line, trace it down to x-axis

The value falls in between 6years and 9 years
