section 3. two ocean beaches are being affected by erosion. the table shows the width, in feet, of each beach measured at high tide where 1995 is represented by year 0:
year number western beach width (in feet) dunes beach width (in feet)
0 100 20
5 90 45
10 80 70
11 78 75
12 76 80
15 70 95
a: describe the patterns shown by the erosion data measurements shown for each of the beaches in the table.
b: between which years will the beaches have approximately the same width?
c: assuming these rates remain constant, what can you do to get a better approximation of when the two beaches will have the same width?
