Limits of accuracy
Determine the upper and lower bounds for measurements that have been rounded, such as identifying the upper bound of a length measured to the nearest metre. Additionally, calculate the upper and lower bounds for results derived from calculations that involve rounded data, including finding the upper bound of the perimeter or area of a rectangle with dimensions rounded to the nearest centimetre, and determining the lower bound of speed based on rounded distance and time values.
