1. The problem statement, all variables and given/known data a) Calculate the time per mode of transport of the lettuce from each starting point. b) calculate the total time required for each complete journey of the lettuce from its origin to Barrie c) d) e) 2. Relevant equations time = distance / speed or t = d/v 3. The attempt at a solution a) and b) - for a) to calculate time per mode of transport, i divided the partial distances by the average speed - for b) to calculate the total time to reach the final destination, i divided the total distance with the average speed please tell me if this is correct. c) this is the one i am having a hard time with, i am doing an online course so i have no help at all. If you could explain what im supposed to do for c) to help me get started, that would be greatly appreciated. d) please tell me if this is correct Route 1. Fuel consumed = (31 km) x (30 L / 100 km) = 9.3 L Route 2. Fuel consumed = (63 km) x (1.2 L / 100 km) = 0.76 L Route 3. Fuel consumed = (81 km) x (30 L / 100 km) = 24 L Route 4. Fuel consumed = (2279 km) x (3.5 L / 100 km) = 80 L Route 5. Fuel consumed = (81 km) x (30 L / 100 km) = 24 L e) please tell me if im right here. Considering that each shipment of lettuce is priced at the same value, I would chose to purchase the lettuce that travels the least distance (which would be the first route of lettuce). Since the lettuce travels less distance, the lettuce would be fresher, and of higher quality. It consumes a small amount of fuel (only 9.3 L) and does not produce a great amount of carbon dioxide emissions. Even though Route 2 consumes less fuel (0.76 L), it still has a longer distance to travel, meanin the lettuce will not be as fresh.
