there are 5 runners in a race. if each runner has the same chance of winning, and they wear shirts with the letters P, Q, R, S, and T, what is the probability that the runners finish the race in the order P, Q, R, S, T?

27 +27 or 27times 2=54

the diffrence is 0

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

answer: math isn’t just mysterious because the majority of us find it so difficult to understand – it’s also the basis of the universe, giving us clues to physical phenomena like the motion of gases in the atmosphere and the way that physical particles interact with each other amid all the possible variables in three-dimensional space.
