To find the unit rate of discovery, we need to divide the total number of new species discovered by the number of years.
Total number of new species discovered: 4,000
Number of years: 2
Unit rate of discovery = 4,000 / 2 = 2000
Therefore, the unit rate of discovery is 2000 new species per year.
About 4,000 new species of marine animals were discovered in the last 2 years. What is the unit rate of discovery?
