About 4,000 new species of marine animals were discovered in the last two years what is the unit rate of discovery A 2 years 4,000 B 4,000 2 years C 2,000 species 1 year D 1 species 2,000 years

Answer 1

To find the unit rate of discovery, we can divide the total number of new species discovered by the number of years.

Given that 4,000 species were discovered in 2 years, we can calculate the unit rate as follows:

\[ \text{Unit Rate} = \frac{4,000 \text{ species}}{2 \text{ years}} = 2,000 \text{ species per year} \]

Thus, the correct answer is:

C: 2,000 species 1 year
