Jillian measured the distance around a small fish pond as 27 yards. which would be a good estimate for the distance across the pond 14 yards 9 yards or 7 yards

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

based on context clues you gave i'm assuming the answer would be c.
