Im not sure about the given data but I plotted the scatter plot based on what I understand on how the data should be presented.
Time (years)
3, 6, 9, 12, 15, 18, 21, 24
Number of participants(x1000)
22, 25, 28, 14, 17, 20,15, 9
Attached is the scatter plot created online.
x = time (years)
y = number of participantep explanation
The answer is C
I pretty sure
0.6/1=120/x
0.6x=120
x=200
200*0.25=50
The answer is 9. 1/3 of the way home is 3 miles 2/3 is 6 miles so we know that the total length of the drive is 9 miles.
