During the fission of an atom of uranium-235, 200 Mev are released. If the average time between generations of fission reaction is 10e-14 seconds and if each fission reaction gives rise to two fissions in the next generation, calculate the time required to go from the first fission to 100 Kw output.

200mev=200000000ev=0.000,000,000,032jouls per sec

1kw=1000joules

31250000000000reactions per second to make 1kw

now my thinking was (long version) 1x2 till i reached 3125000000000000 and took how many x2s it took to reach 3125000000000000 and x taht by 10e-14 but taht didnt work any help is appreaciated

i know its easy (or it should be) i just can't figure it out at the moment
