amistre64 · Answer

this isnt calculus so much as determining the volume and dividing it by its rate of flow

amistre64 · Answer

if we know how many 10s are in the volume:  V/10  then we know how many minutes it will take to drain at 10 per minute.

imstuck · Answer

oh!  So the volume at 75.38 divided by 10 gives 7.538!  OHM you're a Godsend, @amistre64!
