Step-by-step explanation:
Hours per mile
= hours taken / miles walked

Answer:
Step-by-step explanation:
1) in order to graph the required direct line it needed two points:
2) one of these two points is Y-intercept. According to the condition it is (0;1);
3) in order to find the second point, it is enough to apply the given slope: to start in point (0;1), then to move to the left direction (-5 units, move no. 1), then to move up (+7 units, move no. 2);
4) to graph the line between two points (red line); y= -7/5x +1.
All the details are in the attachment.
Slope = Change in Y / change in x
Slope = (16 - -9) / (-2 - 3)
Slope = 25/-5
Slope = -5
6.0000 = 600%

Let's say the father does overtake the boy, the boy would have been travelling for 1 hour and 15 minutes at 8mph, therefor he would have travelled a total of 1.25*8 = 10 m
Now to reach the boy in 15 minutes the father must travel at a speed of 10/0.25 = 40 mph
