Question

I needed to edit this question

Answer 1

Seems like there should be an image.

Anyway, if the distance is 48 mm, we can convert that to AU. Use the fact that 1 mm = 3.6 AU.

So 2mm would be 2*3.6, or 7.2AU.

3mm would be 3*3.6 or 10.8AU.

Convert 48mm to AU in the same way.

Answer 2

Thanks

Answer 3

That's only step 1, though. I'm guessing they want you to have the answer in Km.

Do you know how to finish it...?

Answer 4

Kinda, I get confused on most of it but I can try to get it on my own

Answer 5

Well first step is to convert 48 mm to AU, try that, using what I gave in my post above.

Answer 6

Okie dokie

Answer 7

@agent0smith

Answer 8

Notice that I multiplied by 3.6 to convert mm to AU. Since 1mm=3.6AU.

So convert 48mm to AU.

Answer 9

Um... how did you get that?

Read my above post again. This is step 1.

Answer 10

Okay but first explain how you got 3.2086e-13 ??

Answer 11

That's a pretty huge misunderstanding lol cos I have no clue how you ended at that number :P

So we converted 48mm to 172.8AU.

Now, 1AU = 150 million km.

So if we have AU, and need km, what do you think we should multiply by?

Answer 12

When we converted from mm to AU, we used

1mm=3.6AU

And what did we multiply by?

Use the same logic to see if you can figure out what number to multiply by, when going from AU to km, using

1AU = 150 million km

Answer 13

is it okay if I google how to convert au to km lol because I really don't know on this part

Answer 14

You don't need google, you have the conversions you need already.

When we converted from mm (on the left, below) to AU (on the right, below), what did you multiply by? using

1mm=3.6AU

Notice where you got that number? ie. what side of that equation you found it.

Now we're converting from AU (on the left, below) to km (on the right, below) using:

1AU = 150 million km

Answer 15

Do you see where you can find the number to use to convert?

Answer 16

no :( ughhh

Answer 17

I appreciate you being patient with me

Answer 18

Just tell me what side of the equation you found the number which you used to convert from mm to AU, from

1mm=3.6AU

Answer 19

No, 48 was the amount of mm. What did we multiply that by, to convert.

We had mm, which is on the left. We needed AU, which is on the right. Of this:

1mm=3.6AU

Answer 20

Now we have AU, which is on the left. We need km, which is on the right.

So, using the equation below and the same logic you just used to find 3.6, what do you think we need to multiply by?

1AU = 150 million km

Answer 21

Almost but not quite. It's not just 150.

Answer 22

Now you're further :P look at the equation again.

Answer 23

omg I'm going to die I feel so stupid

Answer 24

lol relax just look at the equation. You had it partially correct. Remember you need to convert from AU to km, using

1AU = 150 million km

Answer 25

The number is right in front of km. Read it out loud and maybe you'll see what you're missing.

Answer 26

I feel mortified, million

Answer 27

Yes :)

So if you need to convert from AU, to km, what do you multiply by?

Answer 28

million?

Answer 29

Look again, you forgot part of it...

1AU = 150 million km

Answer 30

Yes you're right now haha :P

That's how you read unit conversions. Let's say if you needed to convert from inches, to cm. Using the conversion below, how would you convert inches to cm?

1 in = 2.54 cm

Answer 31

you multiply

Answer 32

by?

Answer 33

Yes.

What if you needed to convert km to miles? Using

1 km = 0.62 miles

Answer 34

Good.

So, we have 172.8AU. We need to convert it to km. So try it.

Answer 35

I'm sorry but I gtg, in a few hours I'll be back on. Can you still help me then?

Answer 36

As long as you don't forget everything you just learned :P

Answer 37

Okay, thank you :)

Answer 38

Yes, using 1AU = 150 million km
