(Solved by Humans)-Big fish swim substantially faster than small fish and big birds

Question

Big fish swim substantially faster than small fish and big birds fly faster than small ones.? The speeds of running mammals, however, vary a lot less with body size, although big ones do go somewhat faster. Assume that the energetic cost of transport (cost per distance) varies with (body mass)0.68?and that maximum metabolic rate varies with (body mass)0.81.?

Is the mass-specific cost for a large runner to move a given distance higher, lower, or the same as the cost for a small runner to move that same distance? Explain.

Is mass-specific maximum metabolic rate for a large runner higher
