Consider the following weighted directed graph representing latency (in ms) in a complex computer network from a source server \(S\) to a destination server \(E\).
  1. What is the weight of the directed edge from \(B\) to \(A\)?
  2. Calculate the total weight of the path \(S \to B \to A \to C \to D \to E\).
  3. Find the lowest total weight of a path from \(S\) to \(E\).
