Question

A particular beach is eroding at a rate of 4 centimeters per year. A realtor converts this rate to millimeters per day. Which expression, when evaluated, results in the correct units and numerical value?

Answer 1

4 cm/year * 10mm/cm * 1year/365day ≈ 0.11 mm/day

Answer 2

0.11mm/day

Explanation:

We are given that

A particular is eroding at the rate=4 cm/ year

We have to convert this rate on milimeters per day.

We know that

1 year=365 days

1 cm=10 mm

Rate=
`(4* 10)/(365)`

Rate=
`0.1096=0.11 mm/day`

Answer:0.11 mm/day
