1. The problem statement, all variables and given/known data Estimate the percent error in measuring a distance of about 75cm with a meter stick. 2. Relevant equations 3. The attempt at a solution I'm assuming one could accurately measure this value to a couple mm. so it would be 75+-0.2cm. Now the book gives an answer of 0.13% i just have no clue how they get there. Thanks in advance.
