Two cars started from the same point and traveled on a straight course in opposite directions for exactly 2 hours, at which time they were 208 miles apart. If one car traveled, on average, 8 miles per hour faster the the other car, what was the average speed for each car for the 2-hour trip?

Answer with Step-by-step explanation:

Let speed of one car=x miles/h

Speed of second car=x+8 mi/h

Time,t=2 hours

Distance between two cars=208 miles

We have to find the average speed for each car for 2-hour trip.

Distance=

Distance traveled by one car=2x

Distance traveled by second car=2(x+8)

According to question

Speed of one car=48mph

Speed of second car=48+8=56mph

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.  

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
