You get a GOOD chunk of points for solving. MUST BE 100% SURE OF ANSWER I WILL MAKE BRAINIEST!! Jimmy takes 12 minutes to run 6 times around a 600 meter track. Assuming he runs at a constant speed, how long does he take to run 1 kilometer?

10/3 minutes

Step-by-step explanation:

12 minutes to run 6 times is the same as 2 minutes to run once (ratios)

so it takes 2 minutes to run once around a 600 m track

so 2 minutes/600m = x minutes/1000m

x = 2/600 * 1000 = 20/6 = 10/3

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.
