About 4000 new species of marine animals were discovered in the last two years. What is the unit rate of discovery?

1 answer

To find the unit rate of discovery, we need to divide the total number of new species discovered (4000) by the number of years (2):

Unit rate of discovery = total number of new species discovered / number of years
= 4000 / 2
= 2000 species per year

Therefore, the unit rate of discovery is 2000 species per year.
