Question

help

Answer 1

i got u this looks ez

Answer 2

idk

Answer 3

tet look at the graph you're not that dumb

Answer 4

75

Answer 5

D?

Answer 6

It's 75 or 150

Answer 7

Tet,use the constant of proportionality.Do Y divided by X and figure out what speed the train will go at.

Hint:If it goes through the origin,it is proportional

Answer 8

If you don't know what the constant of proportionality is,I can explain that to you.

Answer 9

@tetsxpreme Do you still need help?

Answer 10

Yeah

Answer 11

\[Speed = \frac{ Distance }{ Time }\]

Answer 12

It looks like Distance is the y-axis (vertical, up n down), and Time is the x-axis (horizontal, left and right).

Answer 13

Just take the a point along that graph and do the division, a given distance and given time

Answer 14

Division? idk how that has anything to do with it, What do i divide?

Answer 15

distance and time?

Answer 16

Well look at the first hour. In one hour the train travels 150km, so you just do 150km (distance) divided by 1 hour (time), and you get a speed of 150km per hour, or 150 km/h

Answer 17

All you need to do is take a point on the second slope / line, and do the same division

Answer 18

Does that make sense?

Answer 19

Oh my mom told me this stuff but she made it a bit confusing

Answer 20

i have notes she wrote but its very confusing

Answer 21

You basically just need a coordinate on the second line. So where a number from the x-axis and y axis on the graph intersect on the line.

Answer 22

This is all I did

Answer 23

but it would be like 225

Answer 24

it saids 2

Answer 25

can you show your math

Answer 26

hours

Answer 27

alright hold

Answer 28

I would just use 3, 2 hour one looks sus

Answer 29

If they wanted you to look at 25distance increments, I think they would've listed it, esp since this graph looks weird.

Answer 30

how did you make a so straight line?
also so i divide something?

Answer 31

Refer to my speed equation, speed = distance / time

Answer 32

take the distance then divide it by time

Answer 33

225/2?

Answer 34

Tet use the line I drew, the 2hour one looks weird

Answer 35

The 3hour one looks clean

Answer 36

so divide 300/3?

Answer 37

yes

Answer 38

That would be 100

Answer 39

yes

Answer 40

ohhh thank youu
