B. A time that is less than a half hour.

Acceleration = Velocity / Time
Greater velocity / Lesser time
Greater Velocity = greater acceleration

Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)

Answer;

An initial velocity that is faster than a final velocity.

Explanation;

-Acceleration is the rate of change in velocity. Average acceleration is the change in velocity divided by the time it took for that velocity change to take place. If magnitude or direction of its velocity changes (speeds up, slows down, or changes direction).

-If final velocity is less than initial velocity, the change in velocity is a negative number and the resulting average acceleration is negative (slowing down in the positive direction) .

-Negative acceleration will also result if the initial and final velocities are both negative and if the final velocity is a larger negative number than the initial velocity (object is speeding up in the negative direction)
