Question

A light bulb consumes 18900 watt-hours in 5 days and 6 hours. How many watt-hours does it consume per day?

Answer 1

18 900 / 5.6 = 3375 watt hours per day

Answer 2

The answer is 3,600.

There's 24 hours in a day and therefore 120 in 5, add 6 gives you 126.

18900/126=150

So 150 kWh used every hour,

150x24= 3600.

So 3600 kWh used every day.

Hope this helps :)
