Answer:comparing the total displacement and tota distance covered by Ben Jerry.

Explanation:

Total distance travelled by both is;

m+n=z

Total displacement of both is;

x+y=z

Therefore;

comparing equation 1 and 2;

x+y=m+n

Displacement is only 30 km but distance traveled is 110 km. The total trip, from start to B; back to C and then finishing at D is 110 km. Their displacement, or distance out of place, is seen at point D, 30 km.
