 // For the piece of code above, read the code and then answer the following questions
 
 // a) How many variable declarations are there in this program?
+// Answer: 6 variable declarations.
 
 // b) How many function calls are there?
+// Answer: 1 function call.
 
 // c) Using documentation, explain what the expression movieLength % 60 represents
 // https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators
+// Answer: The % operator is the remainder (modulo) operator.
+// movieLength % 60 gives the remainder after dividing the total seconds by 60.
+// That remainder is the number of seconds left after removing complete minutes.
+// Example: 8784 % 60 === 24.
 
 // d) Interpret line 4, what does the expression assigned to totalMinutes mean?
+// Answer: (movieLength - remainingSeconds) / 60
+// First it subtracts the leftover seconds so the value divides evenly by 60,
+// then it divides by 60 to get the total number of whole minutes in the movie.
 
 // e) What do you think the variable result represents? Can you think of a better name for this variable?
+// Answer: result stores the movie length formatted as hours:minutes:seconds
+// (for this value: "2:26:24").
+// A clearer name would be formattedTime.
 
 // f) Try experimenting with different values of movieLength. Will this code work for all values of movieLength? Explain your answer
+// Answer: It works for non-negative whole numbers of seconds and correctly
+// splits time into hours, minutes, and seconds.
+// Limitations:
+// - fractional values can produce messy decimals
+// - negative values do not make sense for a movie length.
+// Note: I have changed the movieLength from "8784" to "9325" for testing.
