Work Step by Step
We first multiply the number of emails by the amount of time wasted for each one. Next, we use unit conversion to find:
$$ 265,\:000,\:000,\:000\:\times 4 \ Seconds \\ 1060000000000 \ Seconds \\ \frac{1060000000000}{3600\times \:24} \ Days \\ \frac{331250000}{27} \ Days \\ \frac{331250000}{27\times \:365} \ Years \\ \frac{331250000}{9855} \ Years \\ 33,612\ Years $$
