Ur answer shldnt have hours

#

It’s supposed to be mins and second

patent wagon
#

Time = distance ÷ speed

#

Your answer would be in seconds

#

You need to convert it after

cyan perch
#

How do you get the answer to that question

#

I'm so confused rn

cyan perch
#

Same

#

I know distance divided by time process but I don’t the timing

patent wagon
#

Yh, sorry I couldn't help much

cyan perch
#

It’s fine nws

#

<@&791435371564892232> anyone can tell me how to do this?

slate socket
#

It's just speed = d/t then divide the earth's distance by that speed

#

Make sure to work in si units

candid hinge
#

is it 303030.303?

slate socket
#

(110^3)/3.310^-6 to get speed

slate socket
#

speed of light according to question is 303030303

cyan perch
#

I did the distance divided by the time

Ans divided by the distance to get 303.03 recurring

Where you get 1X10^3

slate socket
#

Kilometers to metre

#

You have to work in SI units

#

and should be -6 btw

#

Nvm I edited it

#

Now once you've gotten the speed

#

The distance between earth and the sun is 1.5x10^11 m (SI units)

#

So you do time = distance/ speed

#

Which is 1.5x10^11/303030303

#

To get 495 seconds

#

Divide by 60 to get mins

#

8.25 mins

#

Which is 8 + 1/4 of a min

#

so it should 8 mins 15 seconds

candid hinge
#

*25 sec

slate socket
#

No

candid hinge
slate socket
#

8.25 mins is 8 mins and 15 secs

slate socket
#

1/4 of 60 is 15

candid hinge
#

Ohhhh! oml tganks!

#

that was silly

cyan perch
slate socket
#

You could but that would only apply to this question cos both quantities are given in km

cyan perch
#

Oh okay

#

Thank you

slate socket
#

I presented a general method which is applicable to all questions

cyan perch
#

Oh okay thank you

#

I over thought it so much

#

@slate socket you able to help me with a other question?

slate socket
#

Yh

cyan perch
#

Can you see it okay?

slate socket
#

I think

#

Could you type it out?

#

The a^5 s cancel out

#

Left with (10a^k)/m

cyan perch
#

Yes

slate socket
#

Comparing like terms you get a^k = a^7 and 10/m = 2/5

#

So k is 7

#

And m is 25

cyan perch
#

Am confused after when we cancel out

#

How you get 25

slate socket
cyan perch
#

Yh

slate socket
cyan perch
#

No

slate socket
#

Ok

#

Do you know what comparing coefficients is?

#

or comparing like terms?

cyan perch
#

Yh they cancel out

slate socket
#

This is basically the same

cyan perch
#

Yh we cancelled out a^5 which I understand am confused after

#

I thought k was 2

slate socket
#

No

#

The only way to get a^7 as needed by the right hand side

#

is k needs to be 7

cyan perch
#

Okay

#

Understand that now

slate socket
#

And the only way to get 2/5

#

Is that 10/m needs to be 2/5

#

so rearranging gives us m is 25

cyan perch
#

Oh yes I understand now

#

Am sorry for longing it I appreciate it alot , thank you
