The cockroach is one of the fastest insects. Write a function which takes its speed in km per hour and returns it in cm per second, rounded down to the integer (= floored).
cockroachSpeed(1.08) == 30
Note! The input is a Real number (actual type is language dependent) and is >= 0. The result should be an Integer.
const cockroachSpeed = s => Math.floor(s / 0.036);
