Question

1000w things use everyday 90 minutes what energy will use in 30 days

Answer 1

90minute=1.5hr
so 30*1.5=45hr
energy=PI
= 1000*45 =45000Wh or 45kWh

Answer 2

Given,

Power (p) = 1000 W.
Time (t) = 90 min
We will convert minutes to hours
=> t = 90/60 hrs. [Since, 1 hours = 60 min]

=> t = 3/2 hrs
=> t = 1.5 hrs

Therefore,

Energy Consumption = Powers x time x No. of days

=> E = (1000 x 1.5 x 30) Wh
=> E = 45000 Wh
or
=> E = 45 Kwh [Since, 1000 Wh = 1 Kwh]
