You can put this solution on YOUR website!
1/r=1/s+1/t....solve for s
1%2Fr=1%2Fs%2B1%2Ft
1%2Fr-1%2Ft=1%2Fs
t%2Frt-r%2Frt=1%2Fs
%28t-r%29%2Frt=1%2Fs
%28%28t-r%29%2Frt%29%5E%28-1%29=%281%2Fs%29%5E%28-1%29
rt%2F%28t-r%29=s
highlight%28s=rt%2F%28t-r%29%29
w=a^2/t.....solve for t
tw=a%5E2t%2Ft
tw=a%5E2
tw%2Fw=a%5E2%2Fw
highlight%28t=a%5E2%2Fw%29
Happy Calculating!!!
