Answer:
3 meters per second.
Step-by-step explanation:
The formula for finding speed is: 
. D is distance. T is time. So in your case, you would divide 6.0 (distance) by 2.0 (time). Your answer is 3. Add meters per second because you divided meters/seconds.
Hope it helps!

Answer k=16
A recipe says to use 3 cups of flour to make 48 cookies.
the number of cookies made, y, to the number of cups of flour used,x .
Than
y = kx
Where k is the constant of proportionality.
48 = 3k
k = 16
Therefore the constant of proportionality is 16.
by separating the variables
∴ y dy = -x dx
integrating both sides with respect to x
∴ ∫y dy = ∫-x dx
∴
finding c using initial condition y(2) = 2.
∴
∴ c = 4
∴
multiplying all the equation by 2
∴ y² = -x² + 8
∴ x² + y² = 8
The resultant equation represents the equation of the circle
with center (0,0) and radius = √8 = 2√2
so, the domain of this function is [-2√2 , 2√2]
