Question

A light bulb consumes 4560 watt-hours in 4 days and 18 hours. how many watt-hours does it consume per day?

Answer 1

The light bulb consumes 960 watt-hours per day.

Step-by-step explanation:

To find the number of watt-hours consumed per day, we need to first convert the given time of 4 days and 18 hours into hours. There are 24 hours in a day, so 4 days is equal to 4 * 24 = 96 hours.

Adding the 18 hours, we get a total of 96 + 18 = 114 hours.

Next, we divide the given watt-hours of 4560 by the total hours of 114 to find the watt-hours consumed per hour: 4560 / 114 = 40 watt-hours per hour.

Since we want to find the watt-hours consumed per day, we multiply this value by 24: 40 * 24 = 960 watt-hours per day.

So, the light bulb consumes 960 watt-hours per day.

Answer 2

This is actually an easy one.

4 day= 24 hours X 4 = 96 hrs.

4560 = 96 hrs.

4560/96 = per hr.

47.5 watts per hr.

Since 1 day = 24 hrs, 47.5 X 24 = 1140 Watts per day.

See? Simple and easy if you solve parts at a time!
