On January 3, 2014, XYZ Corporation bought a truck for $34,000. The truck's useful life was estimated at 60,000 kilometres with a $10,000 trade-in value. Calculate annual depreciation under the units-of-production method and complete the following schedule, assuming that the actual kilometres driven in each year were as shown in the schedule. Round all final amounts to the nearest dollar. For simplicity, assume the truck is depreciated as an individual item and will not be broken down into its parts and depreciated. Actual Dep Accum.

Big Bob's Automotive Repair Shop in Lindsay discovered a leaking underground storage tank on their property today. They are looking for help to characterize the plume and to determine what the potential issues would be if the plume migrated off their property. MW-1 was installed at the source of the contamination and is located 10 meters from the property boundary. MW-2 was installed 8 meters downgradient from MW-1. A water level measurement obtained from the wells indicated a drop in elevation of 0.03 m between MW-1 and MW-2. Laboratory analysis of a water sample indicated a Benzene concentration of 0.95 mg/L at MW-1. The native soil at the site consists of a silty sand with a trace gravel overburden layer, having a hydraulic conductivity of 5.0 x 10^-5 meters/second. Effective porosity for this soil is estimated at 0.29. The Molecular Diffusion (D*) is estimated to be 0.9 x 10^-8 m^2/second. The MECP Standard for Benzene in groundwater for a commercial property in Lindsay is 430 ug/L. Big Bob is retiring in 280 days and wants to know what the potential benzene impacts would be at his downgradient property boundary when he leaves the company. 1. Determine average linear velocity 2. Determine the coefficient of longitudinal hydrodynamic dispersion 2.a Find the value of aL 2.b Find the value of DL
