• This is from a course on special relativity that I'm taking

I'm trying to understand how you get from the first equation to the second equation with cross multiplication as prescribed

I don't even know if this is useful but here is more info:

ΔΤ=30s
Tlo=42h
β=υ:c=30km/s:c
c is the unknown number(also the speed of light)
υ is relative speed(here υ=30km/s)

• I FINALLY FOUND THE SOLUTION

@Rendezvous

Thanks a lot m8. This is probably a piece of cake to you but i was stuck on this for a pretty long time

@thestrangest Man Its pretty simple. I dont know what it has to do with relativity but its just simple elementary maths. I am attaching the cross multiplication part for your convenience:

Thanks dude. All the symbols confused the hell out of me but that is all i needed. This was really helpful

• Maybe you can help

• @thestrangest Man Its pretty simple. I dont know what it has to do with relativity but its just simple elementary maths. I am attaching the cross multiplication part for your convenience:

• @rendezvous naku naku... Ang hangin mo kuya . What about... you solve it? Do it here. I challenge you.

P.S. tss

Dude he already solved it in his 1st post here(the photo), it's really simple but all the symbols just confused mw

• @azriel God you should start reading other posts too. He just said that he understood what I did lol

• Okay okay I must stop now...

It's ok m8, thanks for your support too

• @rendezvous btw, you've got a nice penmanship...

• @thestrangest

What the fuck kind of rocket science is this

I'm taking a very long course on special and general relativity

• @thestrangest so wish I could help you, however math is not my forte... this is math, right?

Physics to be exact but a mathematician can do it just as well

We have the same take on this one.

• Just two questions -
How old are you rn @TheStrangest ?
How old do I need to be to sovle this stuff?

1.I'm 15
2.Age doesn't matter, you just need to learn, memories and understand

• @thestrangest
I'm 15 too.
But this is out of my league shit.
Another But..I'm good at other things so it gets balanced.
And you are intelligent, I have to say.

• @sup thanks

• Nah... It would bebetterif you search it on YouTube. I wanted to help you but typing those on phone is a difficult process.

P.S. If you are going to just base it on the formula given, you don't have to cross multiply it YET. First is distribute the variables through multiplication.
