DESCRIPTION:

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).

For example:

1.08 --> 30

Note! The input is a Real number (actual type is language dependent) and is >= 0. The result should be an Integer.

 

코드

function cockroachSpeed(s) {
  return parseInt(s * 100000 / 3600);
}
