 // d) Interpret line 4, what does the expression assigned to totalMinutes mean?
-//ANSWER: Line 4 with find the remainder whenmovieLength is divided by 60 and assigns the remainder to remainingSeconds (24)
+
 // e) What do you think the variable result represents? Can you think of a better name for this variable?
-//ANSWER: The variable result represents the total lenth of the movie which shows the total hours, minutes and seconds remain in string format.
+
 // f) Try experimenting with different values of movieLength. Will this code work for all values of movieLength? Explain your answer
-//ANSWER: The code semed to  work for all values of movieLength.
