There is therefore a total of 4 trains * 60 wheels per train = 240 wheels at the train station. The final answer: 240. <ibo> Ụgbọ ịnyịnya nke ọ bụla nwere ụkwụ atọ n'ahịrị * ụkwụ ise n'ahịrị ọ bụla = ụkwụ iri na ise. Ya mere, ụgbọ okporo ígwè ọ bụla nwere ụgbọala anọ * wiil iri na ise n'otu ụgbọala = wiil iri isii.
