Question

I will medal the best response.
A satellite can move at 17,000 miles per hour. How many hours will it take to reach a star that is three light years away? Recall that 1 light year = 9.5x10^12 kilometers and 1 kilometer = 0.62 miles. Show your work.

Answer 1

I have no idea how to solve this, but i have a black/tan doxie!!!!

Answer 2

Really?!?! I have a dapple and tan girl, a black and tan girl, and a black and cream boy. And they are all so stubborn.

Answer 3

I sadly one have the black/tan one, and he's a boy named cooper, he is turning 5 in a few days :)

Answer 4

Copper? that's a cute name. Mine girls are turning two in may and my boy is turning one in may. Their names are Piper, Rosie, and Dexter.

Answer 5

Cool! My mom wants to get a dog named Dexter. You are lucky to have a puppy! :)

Answer 6

He is so stubborn though. He like to nip at the girl until they cant stand it anymore and they bite him... then he does it again. He also likes to be held and rests his head on my shoulder. He is just the biggest baby you will ever meet.

Answer 7

Yeah, I also have a vizsla, which is a bigger dog, and my dachshund likes to boss him around, he thinks he's in charge.

Answer 8

We also have a Pitbull/Ikeda who thinks she is a dachshund and tries to lay on our laps.

Answer 9

do your doxies like to stare at the window for hours? Mine will stand on the window ledge looking at birds, wagging his tail.

Answer 10

No and they don't like cars either. Only one like cars and parks but the other two freak out if they know they are going to the park.

Answer 11

Here are pictures and a video of my dogs.

Answer 12

Mine is scared of any other dogs except our other one, Bodi.

Answer 13

Woah, is the one that's your profile pic blind in one eye?

Answer 14

no she just has two different colored eyes.

Answer 15

Copper is sooo cute.

Answer 16

Oh, I when I was a baby, we had a brown doxie named Teapot, and she was blind in one eye.

Answer 17

Oh. I think her two different colored eyes does affect her eyes a little bit but not nearly enough to consider her blind.

Answer 18

Oh, do you have squirrels where you live? Mine is obsessed with chasing squirrels. He has no chance of catching one.

Answer 19

Ya but we have more birds like geese and the one with two different colored eyes think she can kill a goose but when she get close she decides the goose can kill her and runs off. They are also obsessed with cats they just want to play with them luckily they don't want to hurt them.

Answer 20

do you have cats?

Answer 21

I have a hamster and the doxie wants to kill her.

Answer 22

We used to have a hamster and the black and tan one would stare at it for hours.

Answer 23

We have a blue inflatable ball that looks like that hamster ball, so cooper stalks it, thinking its in it

Answer 24

we keep the cage on a dresser so the dogs cant get it

Answer 25

are you there?

Answer 26

Ya.

Answer 27

We had our hamster on the ground.

Answer 28

your dogs never got it?

Answer 29

you should bump your question so someone who knows how to do it can help you, cuz i have no idea

Answer 30

Is is algebra 2?

Answer 31

No they never got it. They're not that smart. And not it is algebra 1.

Answer 32

I am in algebra 1.

Answer 33

Really the lesson is called Scientific Notations.

Answer 34

Scientific notations aren't that hard but this problem is confusing.

Answer 35

i think that maybe if you figure out how many miles per lightyear, then you might be able to figure out the rest easily/

Answer 36

Well I know that
17,000miles= 27,358.848 kilometers
and
3 light year = 28,500,000,000,000 kilometers
but after that I am lost.

Answer 37

I would think you would divide them but the answer is
1.0417105281626e+9

Answer 38

So would it be one hour?

Answer 39

But how can it be one hour if the satellite travels 27,358.848 kilometers in one hour and it has to travel 28,500,000,000,000 kilometers?

Answer 40

idk, here ill tag some people to help @AlexandervonHumboldt2 @TheEdwardsFamily

Answer 41

idk this

Answer 42

Answer 43

@jim_thompson5910

Answer 44

are you able to convert 3 lightyears to miles?

Answer 45

well 1 light year is \[5.87849981\times10^{12}\]miles.

So the formula for 3 light years is \[3(5.87849981\times10^{12})\]

Maybe? I am not sure.

Answer 46

Let's use what they give us

"Recall that 1 light year = 9.5x10^12 kilometers and 1 kilometer = 0.62 miles"

Answer 47

LY = light year

1 LY * (9.5x10^12 km/1 LY) * (0.62 mi/1 km) = 5.89 x 10^12

Answer 48

So 1 lightyear = 5.89 x 10^12 miles (approx)

Answer 49

3 lightyears would be

1 lightyear = 5.89 x 10^12 miles

3*1 lightyear = 3*5.89 x 10^12 miles

3 lightyear = 17.67 x 10^12 miles

3 lightyear = 1.767 x 10^1 x 10^12 miles

3 lightyear = 1.767 x 10^13 miles


with me so far?

Answer 50

yep

Answer 51

Speed = 17,000 miles per hour = 1.7 x 10^4 mph

Answer 52

Distance = Rate * Time

(1.767 x 10^13 miles) = (1.7 x 10^4 mph)*(T)

solve for T to get

T = (1.767 x 10^13)/(1.7 x 10^4)

T = ??

Answer 53

1.0394117647059e+17?

Answer 54

incorrect

Answer 55

when you divide you subtract the exponents

Answer 56

1039411764.71?

Answer 57

1039411764.71 = 1.03941176471 x 10^9

correct

Answer 58

1.03941176471 x 10^9 hours is essentially 1 billion hours (a bit more)

Answer 59

So the satellite had to travel 1.03941176471x10^9=1039411764.71 hours?

Answer 60

roughly, yes

Answer 61

Ok thank you guys so much.
