I understand the problem but not the tests

It seems like the water content halves every ~69 minutes. But the first sentence about 100% and 100 minutes are very confusing. If it is exponential decay, then water should never reach 0.

Rafael S.T. Vieira on 10 Oct 2020

This duration, "in 100 minutes", is misleading, since we are dealing with continuous compouding or exponential decay. Probably a better drescription would be: "A sweater is revolving in a slow low power dryer and losing moisture at any moment at the constant rate 100% of its current moisture content"
