Write the definition of a function typing_speed, that receives two parameters. The first is the number of words that a person has typed (an int greater than or equal to zero) in a particular time interval. The second is the length of the time interval in seconds (an int greater than zero). The function returns the typing speed of that person in words per minute (a float).

The definition of function is as follows:

def typing_speed (number_of_words, Time_Interval):

number_of_words>=0

Time_Interval>0

speed=float (60*number_of_words/Time_Interval)

return speed

Explanation:

Above function is defined step-by-step as follows:

def typing_speed (number_of_words, Time_Interval):

A function named typing speed has two arguments, num_of_words and Time_Interval.

number_of_words>=0

Time_Interval>0

The variable number_of_words is the number of words entered that a person enters, they must be greater than or equal to 0. Where as Time_Interval is the variable for counting the time span in seconds, it must be greater than 0.

speed=float (60*number_of_words/Time_Interval)

return speed

For determining result firstly the seconds are converted int minutes by multiplying with 60 and number_of_words is divided with Time_Interval in order to get words per minute. The return value will give speed which has data type float.
