Acyclist traveling at 26 mph is followed 6 hours later by a car traveling at 78 mph. how long will it take the car to overtake the cyclist?

A cyclist traveling at 26 mph is followed 6 hours later by a car traveling at 78 mph.

Let x be the time taken by the cyclist

Speed of the cyclist = 26 mph

WE know distance = speed * time

so distance traveled by cyclist = 26*x

car started 6 hours later

(x-6) is the time taken by the car

Speed of the car = 78 mph

distance traveled by car = 78(x-6)

when the car overtakes the cyclist then the distance becomes same

so 26x= 78(x-6)

solve for x

26 x = 78x - 468

Subtract 78x on both sides

-52x = -468

Divide both sides b y 52

so x= 9

Time taken by the cyclist  = 9 hours

car started 6 hours later

So time taken by the car = 9-6 = 3 hours

it will take 3 hours for the car to overtake the cyclist

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.  

the answer is d on edge
