Errors and Uncertainty are parts of surveying. These slides start first by defining scale and measurements, then show how to determine the uncertainty in measurements. For making these slides I used some books as well; Surveying_Engineering Surveying 6th edition, Surveying Problem Solving, & Surevying_Elemntary Surveying an introduction to Geomatics_Paul R. Wolf.

A car travels along a straight line at a constant speed of 41.5 mi/h for a
distance d and then another distance d in the same direction at another constant
speed. The average velocity for the entire trip is 25.0 mi/h.
(a) What is the constant speed with which the car moved during the second
distance d?
Your response is within 10% of the correct value. This may be due to roundoff
error, or you could have a mistake in your calculation. Carry out all intermediate
results to at least four-digit accuracy to minimize roundoff error. mi/h
(b) Suppose the second distance d were traveled in the opposite direction; you
forgot something and had to return home at the same constant speed as found
in part (a). What is the average velocity for this trip?
Your response differs significantly from the correct answer. Rework your solution
from the beginning and check each step carefully. mi/h
(c) What is the average speed for this new trip?

A velocity—time graph for an object moving along the x axis is shown in the
figure. Every division along the vertical axis corresponds to 2.00 m/s and each
division along the horizontal axis corresponds to 2.50 s.
(a) Plot a graph of the acceleration versus time.
This answer has not been graded yet.
(b) Determine the average acceleration of the object in the following time
interval t = 12.5 s to t = 37.5 s. m/s2
(c) Determine the average acceleration of the object in the following time
interval t = 0 to t = 50.0 s.
