(e) a teacher instituted a new reading program at school. after 10 weeks in the program, it was found that the mean reading speed of a random sample of 18 second grade students was 90.6 wpm. what might you conclude based on this result? select the correct choice below and fill in the answer boxes within your choice.

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.

to determine the unit cost your would divide the total cost by the number sold.
