QuestionA beach erodes at 4 cm/year. Convert this to mm/day using the correct expression. Which one is right?

Studdy Solution
Based on the analysis of the four expressions, the first expression is the correct one. It correctly converts the rate of erosion from centimeters per year to millimeters per day.
So, the correct expression is$$\frac{4 \mathrm{~cm}}{1 \text { year }} \times \frac{10 \mathrm{~mm}}{1 \mathrm{~cm}} \times \frac{1 \text { year }}{365 \text { days }}$$
