Alaska's tundra is a wet marsh in the summer—it's hard to walk through and slowed them down. It took 1 week to hike the 45.5 miles over the Brooks Range. What was the average number of miles per day that they traveled?

6.5 miles per day

Step-by-step explanation:

First and foremost, we should note that 7 days = 1 week. Therefore, from the question, we are given the information that it took took 1 week to hike the 45.5 miles over the Brooks Range.

The average number of miles per day that they traveled will then be:

= 45.5 miles / 1 week

= 45.5 miles / 7 days

= 45.5/7

= 6.5 miles per day

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.
