Afactory employee spends two hours putting together a car part. a machine can do the same job in thirty minutes. which statement best describes the time-effectiveness of this scenario? the employee is four times as time-effective as the machine. the machine is half as time-effective as the employee. the employee is half as time-effective as the machine. the machine is four times as time-effective as the employee.

The correct answer is

D. The machine is four times as time-effective as the employee.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
