0.1 km because 1meter is a thousandth of a kilometer

what you are asking is power..It is the amount of delivered energy per unit of time..

you could either use joules/second(J/s), watts(W), horsepower(HP), Pferdestärke (PS), cheval vapeur (CV) and foot-pounds per minute… for convenience lets use watts and horsepower

1watt is equal to 1Joule/second and 746 watts equals one horspower
