Answer:
0.7 minute
Step-by-step explanation:
Given that each (1) minute a light use 9.4 watts.
So If the light bulb used a total of 6.58 watts, the minutes was on it is:
[tex]\frac{The total watts used}{The watts used each minute}[/tex]
= [tex]\frac{6.58}{9.4}[/tex]
= 0.7 minute
So the the minutes was on it is 0.7
Hope it will find you well!
