Ryan and Janelle are each driving from a different location to meet. When they each stopped for
lunch at 12 noon, they called each other on their cell phones. Ryan had traveled 245 miles in 3
1/2 hours. Janelle had driven 260 miles in 4 hours. If Ryan and Janelle were originally 910 miles apart
when they had started driving that morning, at what time will they meet?

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.  

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
