now, we get critical points from zeroing out the derivative, and also from zeroing out the denominator, but those at the denominator are critical points where the function is not differentiable, namely a sharp spike or cusp or an asymptote.
so, from zeroing out the derivative we get no critical points there, from the denominator we get x = 8, but can't use it because f(x) is undefined.
therefore, we settle for the endpoints, 4 and 6,
f(4) =3 and f(6) = 7
doing a first-derivative test, we see the slope just goes up at both points and in between, but the highest is f(6), so the absolute maximum is there, while we can take say f(4) as the only minimum and therefore the absolute minumum as well.
I really don't know, what the answer is...
But, I think it is....

Answer:
625 seconds and 10 minutes
Step-by-step explanation:
distancs=S=5km=5000m
average speed=v=8m/s
time taken=t=?
as we know that
average speed=
average speed×time taken=distance covered
here we have to find the time taken
time taken=
time taken=
time taken=625seconds
now we convert seconds into minutes
10 minutes
