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 at 4:10

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"
