Question

A light bulb consumes 1800 watt-hours per day. How many watt-hours does it consume in 4 days and 6 hours?

Answer 1

7650 W-h

Explanation:

1 day = 24 hrs

4 days and 6 hours = 4(24) + 6 = 102 hours

given

24 hrs (i.e 1 day) ------> consumes 1800 W-h

1 hour ------> consumes 1800/ 24 = 75 W-h

102 hrs (i.e 4 days 6 hrs) = 75 W-h x 102 = 7650 W-h
