What is the ratio of the length of one legto the length of the other leg

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

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.
