Using Python:

Write the definition of a function printGrade, which takes one parameter containing a string value and returns nothing. The function prints "Grade: " followed by the string parameter.

Write the definition of a function half which recieves a variable containing an integer as a parameter, and returns another variable containing an integer, whose value is closest to half that of the parameter.

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).
