Answer 1

Explanation:

According to the given data:

A particular beach is eroding at a rate of 4 centimeters per year. A realtor converts this rate to millimeters per day

10 mm = 1 cm

Now convert 4 cm into mm

4 cm= 4*10 mm

4 cm= 40 mm

There are 3365 days in 1 year

Rate to millimeters per day = 40 mm in 365 days

= 40/365 mm per day

= 8/73 mm per day

Divide the term.. We get,

= 0.109589 mm per day .
