Braydon is mixing cement for a large patio. the instructions on the bag say that each batch takes 3 gallons of water per 4 scoops of cement mix. if braydon plans to make 5 batches, how many scoops of cement mix does he need? 0.75 5 15 20

the correct answer is 20

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.
