Answer:
0.56 m/s
Step-by-step explanation:
The average speed of a body tells how fast is the body moving; it is calculated as:
where
d is the distance covered
t is the time elapsed
In this problem, we don't know the distance covered by Ben. Therefore, we will assume that it is 1 km:
d = 1 km = 1000 m
The time elapsed to cover this distance is:
Therefore, Ben's average speed is:
Answer:
I think it is 22 but I might be wrong.
Step-by-step explanation:
Quadratic eq standard form is
Ax^2+bx+c=0
<span>a, b and c are known values.
a can't be 0.</span><span>"x" is the variable
lets take an example
</span><span>x^2 − 4x+2 = 0
</span><span>
x^2-2x-2x+2=0
x(x-2) - 1(x-2)=0
x=1,2
</span>
The correct answer is
<span>5 - 4 + 7x + 1 = 7 x + 1</span>
It is answer #1.
m + g must be less than or = 40 hours
12m + 14g must be greater than or = $250
