3. two ocean beaches are being affected by erosion. the table shows the width, in feet, of each beach at high tide measured where 1995 is represented by year 0.
year number western beach width (in feet) dunes beach width (in feet)
0 100 25
5 90 45
10 80 70
11 78 75
12 76 80
15 70 95
a. between which years will the beaches have approximately the same width?
b. assuming these rates remain constant, what can do you get a better approximation of when the two beaches will have the same width?
just answer a and b that's it. : )
