During a marathon in high ambient temperatures, an athlete produces a total of 2.4 dm3 of sweat per hour to maintain a stable core body temperature.
At a relative humidity of 40%, 85% of this sweat successfully evaporates from the skin to cool the body.
In highly humid conditions where the relative humidity is 90%, only 15% of the sweat evaporates, with the remaining volume dripping off.
Calculate the volume of sweat that evaporates per hour in these highly humid conditions.
