 Precision Percent error What is the percent error for a measurement of 5 miles? First find the greatest possible error. The measurement of 5 miles was made to the nearest whole mile. The greatest possible error is half of 1 mile, which is 0.5 miles. Now find the percent error. $percent\;error\;=\;\frac{greatest\;possible\;error}{measurement}=\frac{0.5}{5}=0.1$ Write the number as a percent. 0.1 → 10% The percent error is 10%. What is the percent error for a measurement of 100 feet?The percent error is %
