@aadi dts wat i wanna know dude...how did ya get 70 for 49 mm??????

dude!!!!!!!!!!! i also explained the second part...look!!!!!!!!!!
ill paste it for u--
1.c=0.7mm
1mm=1/0.7.c
therefore the length for which there is a temperature change=>61-12=49mm
therfore the temperature at this=>49*(1/0.7)=70.c
just do it by simple unitary method
and also since the temperature starts from 0, 70 is ur final ans but cuz the length starts from 12 so u hve to consider 12 in every calculation u make wich evry1 is trying to tell u
Ghost Of Highbury:
sry sry it shud 0 to 70
ok look..
in the range of 12 to 82
they are asking 61
61 is 49 above from 12
so for our scale which 0 to 70, we have to go 49 above from 0 = 0+49 = 49
got it?

@ cooldude chill man...i've seen urs..nd i got it....i said m just looking for alternate ways...!!!stay calm man...take a deep breath in.........and out......cool??!!
@aadi u till didnt get my point man..i know till here...now how did u get 70 fro 49?? is my question.....
nid404:
okay for the second part assume the same way
so
assuming
100o=70mm(82-12)
then xo= 61mm-12mm
x= 4900/70=70o
