Question

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. Western beach width Dunes beach
Year number (in feet) width (in feet)
0 100 20
5 90 45
10 80 70
11 78 75
12 76 80
15 70 95
Assuming these rates remain constant, what can you do to get a better approximation of when the two beaches will have the same width?

Answer 1

graph them and see where the curves intersect
