Rick y Tina caminaron a diferentes tasas constantes. Rick camino 1/2 milla cada 15 minutos, o 1/4 de hora. A Tina le tomo 10 minutos caminar 1/4 de milla. Halla la distancia que camino cada uno en 1 hora. ¿Alguien Sabe La pregunta?

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.  

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
