Answer;
A. the distance that the force move
Explanation;
Simple machines function to make work easier by reducing human effort. These machines may increase the strength of the force, or increase the distance over which the force applied or even change the direction in which the force is applied.
Therefore, when these simple machine reduce strength of a force then the distance over which the force is applied or moves should be increased. Examples of machines that makes work easier by increasing the distance over which the force is applied include, hammers and leaf rakes.

dependent variable:
decrease in volume
Think MPH on a car, The Faster you go the less time it takes to get there. For example, the car again, if a red and blue car are both start in Arizona and want to go to Disney Land they leave the same at the same time but the Blue car goes 50 mph and the Red car 75 mph. The Red car will get there first.
We know, a = Δv / t
Here, a = 1.4 m/s²
Δv = 26-20 = 6 m/s
Substitute their values,
1.4 = 6/t
t = 6/1.4
t = 4.28 s
In short, Your Answer would be 4.28 seconds
Hope this helps!
