You forget to divide by 60

Claudio Gelmi on 24 Apr 2013

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.

fomula's unit was wrong,and precision is harsh.why don't you guys use tolerence?

Dyuman Joshi on 21 Feb 2021

Problem statement is corrected to adjust for units.
Additional test cases with tolerance based test suite are added.

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.
