CHE 3172 Chapter : Exercise 1
Document Summary
Let"s do the calculation with today"s costs (as of 08/22/2011): (a) the estimated costs would be: rent a pickup truck (http://www. uhaul. com/guide/index. aspx?equipment=truck- pickup): the rental costs are . 95 plus sh. 59 per mile. We are driving 320 km (2- way trip). Therefore the total rental costs are: (. 95) + (sh. 59/mile) x (160 km) x 2 x (0. 6214 miles / km) = . 27: fuel costs: we need fuel for 320 km, or 198. 8 miles. The pickup truck makes roughly 19 mpg (http://www. uhaul. com/guide/index. aspx?equipment=truck- pickup), and gasoline costs roughly . 31/gallon. So the fuel costs are: (198. 8 miles) x (1 gallon / 19 miles) x (. 31/gallon) = . 64: total costs = . 91 (let"s add . 09 for lunch, so that the total costs are. ~. 00) (b) we again assume that we can carry 20 books (1 book ~ 1 kg, or 2. 2 lbs) per trip.
