/* Passage Counter - This is a feature utilized by most blogs to calculate reading time. Create a function which calculates the time to read a text in seconds, if it takes over 60 seconds to read a passage return the time to minutes.

The average human reads 200 words per minute.

Algo >>>  split the passage into an array of words > Clean up each word by trimming it of any extra space > then find the average time to read the total number of words in the passage, assuming the number of words a human reads per minute is 200

The resulting time is returned in minutes or seconds if less than a minute. All figures are rounded to whole numbers.
