What's the estimate for 11 1/5 and 3.98

7

Step-by-step explanation:

Estimate 11 1/5 to 11.

11.2 ≈ 11

Estimate 3.98 to 4.

3.98 ≈ 4

Estimate the difference.

11 - 4 = 7

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.
