Q. What is the greatest possible error for a measurement of 5 kilometers?____ kilometers
Determine Precision: Determine the precision for the measurement of 5 kilometers.Since the measurement is given as a whole number without any decimal or fractional parts, the precision is to the nearest kilometer.Precision: 1 kilometer
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 kilometer=0.5 kilometers
