Q. What is the greatest possible error for a measurement of 5 miles?
Determine precision: Determine the precision for the measurement of 5 miles.Since the measurement is given as a whole number without any decimal or fractional parts, the precision is to the ones place.Precision: 1 mile
Calculate error: Calculate the greatest possible error based on the precision.The greatest possible error for a measurement is half of the unit of precision.Greatest possible error =2Precision=21 mile=0.5 miles
