You run 2 1/2 miles as a part of an exercise routine. You run 1/3 of that distance on a hill. You run down a slope for the last 1/2 of the hill. On how many miles of your run do you run down the slope? Write your answer as a fraction or mixed number in simplest form.

Given:

Total distance for daily exercise is  .

You run 1/3 of that distance on a hill.

You run down a slope for the last 1/2 of the hill.

To find:

The distance you run down the slope.

Solution:

We have,

Total distance

You run 1/3 of that distance on a hill.

Distance on a hill

You run down a slope for the last 1/2 of the hill.

Distance you run down the slope

In cannot be expressed as mixed fraction because 5<12.

Therefore, the distance you run down the slope is .

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.  

i hope this is what you were looking for.
