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:
```python
cockroach_speed(1.08) == 30
```
Note! The input is a Real number (actual type is language dependent) and is >= 0. The result should be an Integer.
import math
def cockroach_speed(s):
    return (math.floor(s*27.7778))

def cockroach_speed(s):
    return (math.floor(s*27.7778))
