Question

a light bulb consumes 6300 watt-hours in 3 days and 12 hours. how many watt-hours does it consume per day?

watt-hours per day

Explanation:

Step1: Convert time to days

12 hours is $\frac{12}{24} = 0.5$ days. So 3 days and 12 hours is $3 + 0.5 = 3.5$ days.

Step2: Calculate consumption per day

Use the formula: Consumption per day = Total consumption / Total days. So it's $\frac{6300}{3.5} = 1800$.

Answer:

1800
