The speed of a locomotive without any wagons attached to it is 40 kmph. It diminishes by a quantity which is proportional to
the cube root of the number of wagons attached, i. e. the speed of
the locomotive is 34 kmph when 27 wagons are attached. What is
the maximum number of wagons that can be attached, so that
speed does not go below 30kmph?
