Respuesta :

By definition, the power is given by:
 [tex]P = \frac{W}{t} [/tex]
 By definition, the power is given by:
 Where,
 W: Work done
 t: time
 Clearing the time we have:
 [tex]t = \frac{W}{P} [/tex]
 Substituting values we have:
 [tex]t = \frac{1800000}{15000} [/tex]
 Making the corresponding calculations we have:
 [tex]t = 120s[/tex]
 Answer:
