If he walks at a speed of 3 miles per hour and runs at a speed of 5 miles per hour, how many hours each week does he spend exercising? Let's be accurate as possible. <ibo> Tony na-emega ahụ kwa ụtụtụ site n'ije ije ruo kilomita atọ na-ebu akpa dị kilogram iri abụọ na ise n'úkwù, mgbe ahụ, ọ na-agba ọsọ ruo kilomita iri ọzọ n'ebughị akpa ahụ.
