1 day = 24 hours
So 1440 watt-hours in 24 hours = 1440 / 24 = 60 watts per hour
5 days x 24 hr day-1 = 120 hrs + 16 hrs = 136 hours
Consumption: 60 watts per hour x 136 hours = 8160 watt-hours

Answer: 8160
Multiply 1440 by 5 days = 7200.
Divide 1440 by 24 hours in a day = 60 per hour
Multiply 60 by 16 hours: 960
Add 7200 + 960

1 day = 1440
24 hours = 1440
1 hour = 60 watts
Hence 5 days = 5 times 1440 = 7200 watts
16 hours = 16 times 60 = 960 watts
Total = 8160 watts

8160... 1440 X 5 =7200
1440 / 24 = 60
60 X 16 = 960
1440 + 960 = 8160

1440 / 24 = 60
60 x 16 = 960
1440 x 5 = 7200
7200 + 960 = 8160 watt-hours

5 days and 16 hours
This is equivalent to:
5 16/24 days
= 5 2/3 days
5 2/3 x 1440
= 5 x 1,440 + 2/3 x 1,440
= 7,200 + 960
= 8,160 watt-hours

1440 Watt-hrs / 24 hrs per day = 60 Watts per hr
5 days * 24 hrs per day + 16 hrs = 136 hrs
136 hrs * 60 Watts per hr = 8160 Watts

it will still consume 1440 watt-hours but will have consumed 1440x 136 =195840 watts

8 160
1440/24= 60
1440*5 = 7200
60*16=960
7200 + 960 = 8 160
