Question 13
A batch of fresh fruit is 65% water by mass. After drying for 19 hours, it is 25% water and weighs 15.2 kg less than at the start. How many additional minutes of drying are needed for it to be 5% water? The mass of water removed each minute is constant.
Model clarification: drying removes only water; the mass of dry fruit matter stays unchanged.
