Diane drive 819 miles in 13 hours at the same rate how long would it take her to drive 567 miles.

9 hours

Step-by-step explanation:

We can use a ratio to solve

819 miles        567 miles

=

13 hours           x hours

Using cross products

819 x = 567*13

Divide each side by 819

819x/819 = 567*13/819

x =9

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
