6. In a Bio 207 lab you determine that the cost of transport for two fish from different species is 1 kJ/km for fish one, and 10 kJ/km for fish two. Provide an estimate of the swimming speed of each fish assuming that a) both fish have the same metabolic rate; b) fish two has a metabolic rate 10 times higher than the metabolic rate of fish one; and c) fish one has a metabolic rate that is 100 times smaller than the metabolic rate of fish two. Note that the ratio of metabolic rate to speed defines the cost of transport in units of energy/distance.
