Question

A coastline has receded 450 centimeters in 9 years. Each year, the coastline recedes the same distance. One meter is equal to 100 centimeters. How far does the coastline recede each year, in meters?​

Answer 1

Answer:0.50 meters

Explanation:

Answer 2

We need to determine the length per year, so take the ratio of 450/9 and simplify it.

r = 450cm/9yr
r = 50cm/1yr
r = 50cm

50cm/100cm = 1/2

So, the coastline recedes 1/2 meters every year.
