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:
\(\frac{4 cm}{1 year}\times \frac{10mm}{1 cm} \times \frac{1year}{365 days}\)
Step-by-step explanation:
A particular beach is eroding at a rate of 4 centimeters per year.
So, if we want to calculate it as per day we will do:
The expressions are not given, but the conversion rates are standard, so there can be only one answer.
The correct answer is =
\(\frac{4 cm}{1 year}\times \frac{10mm}{1 cm} \times \frac{1year}{365 days}\)
= 0.109 mm per day
