Q. What is the percent error for a measurement of 2 kilometers?If needed, round your answer to the nearest hundredth of a percent.___%
Find Error for 2 km: Find the greatest possible error for 2 kilometers.Divide the smallest unit of measurement by 2.Since the problem does not specify the smallest unit of measurement, we will assume it is 1 meter (which is a common smallest unit for kilometer measurements).1 meter = 0.001 kilometersGreatest possible error: 0.001 kilometers
Calculate Percent Error: Calculate the percent error.We have: Measurement: 2 kilometers Greatest possible error: 0.001 kilometers Percent error = (Greatest possible error/Measurement)×100%Percent error = (0.001/2)×100%
Round Final Percent: Round the answer to the nearest hundredth of a percent if necessary.The calculated percent error is already at the hundredth of a percent, so no rounding is needed.Final percent error = 0.05%
