Solve the all given parts of following question:

Question: A marathon runner completes a 42.188-km course in 2 h, 25 min, and 33 s. There is an uncertainty of 22 m in the distance traveled and an uncertainty of 1 s in the elapsed time. (Give all answers to the appropriate number of significant figures. Note that uncertainties should be reported to one significant figure and percent uncertainties should be reported to two significant figures.)

Part I: Calculate the percent uncertainty in the distance.
