1. The problem statement, all variables and given/known data The carbon dioxide emissions for each segment are approximately 0.01 tonnes for each of the train and truck portions, and 1.08 tonnes for the plane portion. Calculate the carbon dioxide emissions for each route, from its origin to its final destination. - All variables that are given are in the thumbnail that I attached. That was the table the question gave me. Im not exactly sure how I go about calculating the carbon dioxide emissions. The way the question is worded also doesnt make much sense to me either, so its not helping with trying to decipher whats going on. 2. Relevant equations v = d / t d = v* t t = d / v slope = y / x y2 - y1 / x2 - x1 a = v2 - v1 / t2 - t1 a = v / t Measurement of fuel consumption: L / 100km L being liters of fuel 3. The attempt at a solution I tried using the measurement of fuel consumption to calculate what the emissions were going to be but I dont believe I did it right, partly because I dont fully understand the question. Does 0.01 tonnes refer to the total amount of emissions used for a truck/train journey? Or is that referring to the amount of tonnes used per 100km when looking at the equation???
