A, b and d
Competition for fix resources of course increases the
energy expenditure needed to gather those resources and leaves less for a
given population. A lower amount of sunlight or water also contributes
to decreased energy which lowers growth. Finally, small borders limit
growth in that population density can only go so high before the death
rate increases beyond the birth rate.
I guess the problem is asking for the distance between Earth and Mars in Astronomical Units (AU).
Since

and the distance between the two planets is

we can convert this distance into AU by using the following proportion:

from which we find
Answer:

Explanation:
Hello.
In this case, since the velocity is computed via the division of the distance traveled by the elapsed time:

The distance is clearly 1743 km and the time is:

Thus, the velocity turns out:

Which is a typical velocity for a plane to allow it be stable when flying.
Best regards.
Speed(S) = Distance(d) ÷ Time(t)
S = d/t
