A) The rhino's average velocity on the x-axis is 
. The position x after time t=21.5 s can be found by using the relationship:
where we used
as the x-position at time t=0, since the rhino was at the origin.
SImilarly, the average velocity on the y-axis is
, and the y-position after time t=21.5 s can be found by using:
where we used
since the the rhino was at the origin at time t=0.
b) The distance of the rhino from the origin can be calculated by calculating the resultant of the displacement of the rhino on both axes:
where we used
