It is well known that superman can withstand as much as 3 grams of Green Kryptonite indefinitely. However, exposure to more than 3 grams for more than 13 hours is fatal. Assume that Kryptonite decays at an hourly rate of 5.35%

If superman is trapped in a room with 6 grams of Kryptonite, will he survive?

3 = 6e^-.0535t
-.0535t = ln .5
t = ln .5/-.0535 = 12.9 hrs

so what do you think?
