2. Eugenia wants to find out how fast she walked along a hiking trail that took her 1.5 h to complete. She counted the number of steps with a pedometer and got 10,000 steps. In order to calculate the distance she walked, she estimated the length of her stride. She walked 10 steps three times at her usual rate and measured the distance with a measuring tape (the smallest division is 1 cm) and got 754 cm, 748 cm, and 739 cm. Find the length of her stride. What are the absolute and relative uncertainties in that measurement? What is the absolute uncertainty in Eugenia’s time measurement?
