 // 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?
-
+// There are 7 variable declarations: movieLength, remainingSeconds, totalMinutes, remainingMinutes, totalHours, result
 // b) How many function calls are there?
-
+// There is 1 function call: console.log(result)
 // c) Using documentation, explain what the expression movieLength % 60 represents
 // https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators
+// The % operator is the remainder operator. movieLength % 60 finds the remainder after dividing movieLength by 60.
 
 // d) Interpret line 4, what does the expression assigned to totalMinutes mean?
-
+// Calculate the total number of complete minutes.
+// First, subtract the remaining seconds from the movie length,
+// leaving a number that can be divided exactly by 60.
+// Then divide by 60 to convert seconds into minutes.
 // e) What do you think the variable result represents? Can you think of a better name for this variable?
-
+// result represents the movie length converted from seconds into hours, minutes and seconds.
 // f) Try experimenting with different values of movieLength. Will this code work for all values of movieLength? Explain your answer
+// The code works correctly for positive whole numbers of seconds.
+// However, it may not give a useful result for negative numbers,
+// decimals, or values that are not numbers.
