Crane Inc. purchased a transport truck for $190,800. The company expected the truck to have a useful life of 8 ears or 236.800 kilometres, with an estimated residual value of $13,200 at the end of that time. During the first and second years, the truck was driven 29,800 and 32,000 kilometres, respectively. Calculate the depreciation expense for the second year under the straight-line, units-of-production, and double-diminishing-balance methods.
