I recently came across this question in a chemistry text book. It's seems relatively simple but I get an answer different to the one in the book and can't understand why.
A 2000MW power station has an energy output of 2000MJ/s. How long would it take to generate 3.39x1016J of energy?
First, I converted joules to mega joules giving: 3.39x10^10J
Then, 3.39x10^10 / 2000
Giving, 16950000 s.
Which works out at about 196 days.
The answer the book gave was 175 days.
Thanks for any help.
