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 integer greater than or equal to zero) in a particular time interval. The second is the length of the time interval in seconds (an integer greater than zero). The function returns the typing speed of that person in words per minute (a float).

     public static double typing_speed(int no_of_words, int no_of_sconds){

         double time_in_minutes = (double)no_of_sconds/60;

         return  (no_of_words/time_in_minutes);

     }

Explanation:

public class num10 {

     public static void main(String args[]) {

         int numWords = 17;

         int numSecs = 128;

         System.out.println("The typing speed per minute is "+typing_speed(numWords,numSecs));

     }

     public static double typing_speed(int no_of_words, int no_of_sconds){

         double time_in_minutes = (double)no_of_sconds/60;

         return (no_of_words/time_in_minutes);

     }

   }

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
