The answer is A.
Speed = distance / time
Speed = (4*400) / (6*60) (6*60 to turn minutes to seconds)
Speed = 1600 / 360
Speed = 4.44
Velocity = displacement / time
since she is running in a circle, she stops where she started making he displacement 0
Velocity = 0 / 6*60
Velocity = 0

Answer:x=-3
Step-by-step explanation:
(-x-2) (x-4) are the factor of this equation
The difference of the given functions is x^2 + 10
<h3>Difference of functions</h3>
Given the following functions
f(x) = 2x^2 + 3 and
g(x)=x^2-7
Take the difference
(f-g)(x) = 2x^2 + 3 - (x^2 - 7)
(f-g)(x) = 2x^2 - x^2 +3 + 7
(f-g)(x) = x^2 + 10
Hence the difference of the given functions is x^2 + 10
