i think it was much less, i don't remember my answer but it had to be close to the value given in the next question that says the acceptable number is 1.5 something like that. don't know
my value was 0.75 something like that...
i used the equation- x=x0 exp(-lambda*t)

yeah that's the right formula but due to the limited time i had i multiplied the 8 hrs by 60 and another 60. probably another mark there. ok that's enough for me
