question 1: If you were to summarize your answers to part A and B to express the total distance walked by the student, with associated uncertainties, what would that be? Enter the distance and the associated uncertainty, separated by a coma. For instance, if your answer is 1.1-0.2, enter 1.1,0.2 in the box below.
Question 2: Consider the uncertainty on the distance walked in the first leg of the trip (0.1 m), the uncertainty on the distance walked in the second leg of the trip (0.2 m) and the uncertainty you found for the overall distance walked, in part C. What rule applies to uncertainties when adding numbers like we did in this example?
