For this case, what we must do is calculate the speed of the runner.
We have then that the speed is given by:

Where,
d: distance
t: time
Substituting values we have:


Answer:
the runners unit rate is:

Length= y in.
Width= (y-6) in.
Perimeter = 2(L*W)
Perimeter=2L+2W
68in.=2(y)+2(y-6)
68=2y+2y-12
68=4y-12
68+12=4y
4y=80
y=20
Length= 20 inches, width =14 inches
Answer:

Step-by-step explanation:
remember that,

given that,
thus substitute:

divide both sides by 4/3π:

cubic root both sides:

and we are done!
Answer:
4
Step-by-step explanation:
Slope is x2-y2/ x1-y1
So, its 6-10/1-2
or, -4/-1
Or 4.
Hope this helps you!

Answer:
Step-by-step explanation:
I'm guessing you want the volume?
so for a triangle it's 1/2 base * height for the area
1/2 * 8 * 3 = 12
12*20=240 m^3
