what is the shortest possible time in which a bacterium could drift at a constant speed of 3.5mm/s across a petri dish with a diameter of 8.4cm

  • physics -

    (8.4 cm)/(0.35 cm/s) = ___ seconds

    I don't know why they call it the "shortest" time. It is the required time, if drifting at that speed across the dish along a diameter.

  • physics -

    24s
