Answer:
Dark and Light is always there
Step-by-step explanation:
Think of it like an Angel and a Demon so basically there are colors all around us, and one of those colors is black so even if you were in the day if you block al sunlight out it would be dark then again there is artificial light so even if all light is blocked out light will always be there and Dark will also always be there hope this helped BTW I’m a fifth grader who goes to seventh grade sooo this should be correct(if you don’t understand I’m basically saying that the speed of Dark and Light is equal.
