I have three questions below. I would like to understand how their respective answers were reached, this is a question in my current class and everyone in the class has A-Level mathematics experience - I have asked my tutor to explain but they talk very technically and I'm at a loss. I was hoping to get a simple answer from someone in this community, this formula is important to a project I am making - I am making an algorithm that sniffs packets and converts the delay result as png. I need to understand the maths behind it.
For Question 1: Why is the answer 2ms (Why 2m rather than just m) and what does the "Over" signify?
For Question 2: Why is the answer 2LR (Why 2L rather than just L)?
For Question 3: And I just can't figure out what this answer means or how it is reached.
