Victoria walked a mile in nineteen and a third minutes. it took amanda only thirteen and a half minutes. how much longer did victoria take?

6.30

Step-by-step explanation:

19.20-13.30=6.30

Well, if you subtract 2 from 3 you will need to borrow from the next door and you will get 12. The 9 will turn to a 8 after you borrow 1 from it.

Then you subtract and get 9.

After that you subtract 8 and 3 and you will get 5.

Then the 1-1=0

So it is 5.90

You will need to convert 5.90 into time and you will get 6.30 since you subtracted .60,its a minute, from .90 and then it will be .30 You need to add the one in 5 and you will get 6.30

answer: idk

step-by-step explanation:

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.
