2. The Hungry Tuna
What is the minimum number of ï¬sh a 3m long blueï¬n tuna wouldhave to eat to fuel a non–stop voyage across the Atlantic in twoweeks if they traveled at 14.88 km/hr on average? How often wouldprey ï¬sh need to be captured during this voyage? Assume a traveldistance of 5000 km and that the tuna can extract 1000 kJ of energyfrom each prey ï¬sh. You may also assume that the body is ellipticalin cross–section, that the body height is 1/4 the body length andthe body width is 1/8 the body length.
Edit: The mass of the tuna is not given. This problem issolvable with the information given above.
.
Answer: The tuna must eat at least 57 ï¬sh.Given that this occurs over 2 weeks, the tuna must eat at least4.05 ï¬sh each day. But how do I get to this answer? Pleaseshow work and formulas used to get the provided answers. Thankyou!
