You forget to divide by 60

I think there is a 2 missing in one of the answers...they are not consistent...

Chintan on 25 Apr 2013

@Dan- Yes, Thanks.
@Claudio - For specific formula, answers are consistent but correct final answer in both cases should be divided by 60 as Dan mentioned.

I believe the test cases give the power in Joules/minute, rather than the requested units of kW.

The test suite is generating wrong answers!!

Aaron on 16 Apr 2015

Test suite answers need to be /60 and are in watts, not kW.
