Question

A chemist is conducting an experiment which involves a certain chemical reaction. He begins the experiment with 824 milliliters of the chemical, which is consumed by the reaction at a varying rate that is no more than 12 milliliters per minute. Partway through the experiment, the chemist measures the amount of chemical remaining. If there are 752 milliliters of the chemical left, what is the smallest number of minutes that could have passed?

Answer 1

That'd be 6 minutes because 824-752 is 72 and that divided by 12 is 6
