The designated course for a 6 kilometer road race has the runners going 4.5 km west and then 1.5 km north,
where the finish line is located. a less-than-honest contestant in the race runs 2.5 km west and then decides
to head straight toward the finish line. what distance does this wanna-be actually cover during his race?

4.0

Explanation:Since he ran 2.5 and then ran north you-add 1.5 plus 2.5 =4.0

he made 11 calls in one day

  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.
