Q. What is the greatest possible error for a measurement of 8 miles?____ miles
Determine precision: Determine the precision for the measurement of 8 miles.Since 8 is a whole number without any decimal or fractional parts, it is precise to the ones place.Precision: 1
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=0.5 miles
