1. The problem statement, all variables and given/known data On a recent trip to Moncton my driving log reads as: 1 hr, 0km 20min, 10km 1hr, 80km 20min, 0km 1hr, 110km 40min, 70km 15min, 10km a) Plot the distance as a function of time and determine a good linear approximation. (d=at+b) b) Since there are a number of straight lines that might fit this data, what mathematical test could you think of to determine what might be the "best fit" to the data. c. Enter into excel and fit a 'treadline' to data. d. How does the treadline match with my answer. e) Could you use the approximation to estimate the time required to travel to st John (412km). Explain. 2. Relevant equations 3. The attempt at a solution Already have it graphed and given a line of best fit. Really need help with B Entered into excel already Should I compare the slope and y-intercept? are there toomany variables to include that would make this approximation useless? or could you use it. Thanks, Just need a steer in the right direction.
