Problem 1

A chemical is poured into cylindrical and conical flasks at a constant rate. It takes 88 seconds to fill each flask to the brim. If d(t)d\(\left\)(t\(\right\)) represents the depth of the chemical at any time tt in 0≤t≤80\(\leq{t}\]\leq{8}\), for which flask does d′d^{\(\prime\)} reach an absolute maximum on the interval [0,8]\(\left\[\lbrack\)0,8\(\right\]\rbrack\)?
