 // Questions
 
 // a) When formatTimeDisplay is called how many times will pad be called?
-// =============> write your answer here
+// 3 times: the return statement contains 3 pad calls within the formatTimeDisplay function.
 
 // Call formatTimeDisplay with an input of 61, now answer the following:
 
 // b) What is the value assigned to num when pad is called for the first time?
-// =============> write your answer here
+// num = 0 as when the input is 61 seconds, remainingSeconds = 1, totalMinutes = 1, remainingMinutes = 1, totalHours = 0. 
+// totalHours = (totalMinutes - remainingMinutes) / 60 = (1 - 1) / 60 = 0 / 60 = 0 (dividing once into minutes and once into hours).
 
-// c) What is the return value of pad is called for the first time?
-// =============> write your answer here
+// c) What is the return value of pad when called for the first time?
+// "00" as num is 0, and padStart(2, "0") adds a leading zero to make it two digits.
 
 // d) What is the value assigned to num when pad is called for the last time in this program?  Explain your answer
-// =============> write your answer here
+// The last time pad is called, num is assigned the value of remainingSeconds, which is 1.
+// Go to line const remainingSeconds = seconds % 60; and use input of seconds = 61 to calculate remainder of 61/60 = 1
 
 // e) What is the return value assigned to num when pad is called for the last time in this program?  Explain your answer
-// =============> write your answer here
+// The last time pad is called, it uses remainingSeconds which is 1
+// The call is pad(1) which converts to a string and adds a leading 0 if there's less than 2 characters
+// So, the return value is "01". 
+// The final formatted time string for an input of 61 seconds is "00:01:01".
