Resposta:

44,76 Kwh

Explicació:

1 cavall = 746 watts

Per tant, 30 cavalls es convertiran en:

30 * 746 = 22380 watts

Temps = 2 hores

La quantitat d'energia consumida s'obté mitjançant la relació:

Energia consumida = Potència * temps

Energia consumida = 22380 watts * 2 hores

Energia consumida = 44760 Wh

A quilowatts (Kwh)

44760 Kwh / 1000 = 44,76 Kwh
