Students will be able to:

## Requirement:

Remix the program provided at https://scratch.mit.edu/projects/165770195/. Write a program that takes the durations of two video clips as the input (asks the user to enter the number of hours, minutes and seconds) and displays the total duration as the output. For example, for planning the length of clips in a film or songs in a playlist we might need to add the length of the first clip which is 32 minutes, 21 seconds (0:32:21) to the length of another clip which is 33 minutes and 20 seconds. Each time input (hours, minutes and seconds) are entered each on a different line. The output of your program should be 1 hour, 5 minutes and 41 seconds.

## Testing examples:

Your program should display the outputs shown in this table for the given inputs provided;

Input Output
0:32:21
0:33:20

1:5:41
3:59:59
2:13:3

6:13:2
4:59:59
2:59:59

7:59:58

Hints
• If total seconds (sum of the number of seconds from the first clip and the second clip) is greater than 59, increase total minutes (sum of minutes from the first clip and the second clip) by 1 and set total seconds to total seconds modulo 60.
• If total minutes (sum of the number of minutes from the first clip and the second clip) is greater than 59, increase total hours (sum of hour from the first clip and the second clip) by 1 and set total minutes to total minutes modulo 60.
