 // 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, and maybe the console.log has none.
+// (If counting only const declarations, there are 6: 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
+// % is the remainder operator. It gives the remainder when movieLength is divided by 60.
+// For 8784 seconds, 8784 % 60 = 24, so there are 24 seconds remaining after full minutes are counted.
 // https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators
 
 // d) Interpret line 4, what does the expression assigned to totalMinutes mean?
+// totalMinutes = (movieLength - remainingSeconds) / 60
+// This removes the extra seconds left over after full minutes are taken out, then divides by 60 to convert the remaining whole seconds into total minutes.
+// For 8784 seconds, this gives 146 minutes.
 
 // e) What do you think the variable result represents? Can you think of a better name for this variable?
+// result represents the time formatted as hours:minutes:seconds.
+// A better name could be timeString or formattedTime.
 
 // f) Try experimenting with different values of movieLength. Will this code work for all values of movieLength? Explain your answer
+// It works for any non-negative number of seconds, because it calculates hours, minutes, and seconds using division and remainders.
+// It will not format correctly for negative values, and it assumes the value is in seconds rather than another unit.
