50mph
Step-by-step explanation:
The image of the motion of Paul's derive is attached already.
From the line graph we can obtain a lot of information that will help us unravel the average speed of Paul within the given time frame.
What is average speed?
Average speed is the rate of change of total distance covered with time taken .
Average speed =
To find the total distance covered;
Distance at time 1 = 75miles
Distance at time 4 = 225miles
Distance covered between 1 - 4 = 225 - 75 = 150miles
Time taken for the journey = 4 - 1 = 3hrs
Input the values in the equation;
Average speed = = 50mph

<u><em>Answer:</em></u>
The mean will decrease
The median will remain the same
<u><em>Explanation:</em></u>
<u>1- checking the mean:</u>
<u>Mean of the salaries is calculated as follows:</u>
<u>Now, we can note that two parameters affect the mean, let's consider each:</u>
<u>a. Number of employees:</u>
We are given that one employee is replaced with another. This means that the number of employees did not change
<u>b. Sum of salaries:</u>
We are given that a person earning $15 left and the new person earns $7. This means that:
New sum of salaries = old sum of salaries - 15 + 7 = old sum of salaries - 8
This means that the sum of salaries decreased by 8
<u>Now, for the mean:</u>
We can conclude that since the numerator decreased while the denominator stayed the same, the mean will decrease
<u>2- checking the median:</u>
In the whisker plots, the median is represented by the vertical line inside the plot.
<u>In the first plot,</u> we can note that the vertical line is nearly half the distance between 9 and 10. This means that, for the first plot, the median is approximately 9.5
<u>In the second plot,</u> the place of the median is unchanged. It is still approximately midway between 9 and 10 which means that the median in the second plot is approximately 9.5
Therefore, the median of the data remains unchanged.
Hope this helps :)
