HELPP PLSS I WILL GIVE U BRAINLIEST not really sure if this is supposed to be in the math section but its about graphs

i have this graph for science and i need to find the speeds but im not sure if im doing it right

the numbers that i have right now are

A) 0-8 = 8/2 = 4 m/m

B) 0-2.5=0/2.5=0m/m

C) 2.5-3=10/3=3.3m/m

D) 3-3.5=15/3.5=4.3m/m

m/m = miles per minute
and A, B,C, and D are like when what i think the speeds are of the four lines

((also if someone could help me on my other question in math that would be great)

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

she gotta workk that a 2

step-by-step explanation:

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
