(c) Worker A, weighing 65kg, has a VO2max of 65mL/kg/min and worker B, weighing 104kg, has a VO2max of 52mL/kg/min. When walking steadily at 5km/h with no extra load, A is working at 30% of his VO2max, and B at 40% of his VO2max. If each of them has to carry a 30kg load that requires the consumption of one additional liter of oxygen per minute, which worker will tire more quickly? Provide a brief calculation to support your choice. (15 MMarks)
