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)

@thestrangest @Sir-Devil and @Lucifer_,

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:

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.

@azriel Omg whats there to even to discuss in it. Its simple maths, kids of 4th grade are there to solve it. Its not even worth looking over lmao.
@TheStrangest is just having a small confusion thats it.

To be clear i made this post on my phone and wrote everything on my phone

[Azriel]

@rendezvous if you want him to understand, you must show him the step by step process... lels

[Azriel]

@thestrangest sorry but I suck at typing T.T

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

[Unknown4123]

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

[Azriel]

Okay okay I must stop now...

[TheStrangest]
