I am a high school administrator creating a Google Form Hall Pass. A student will complete the form once when they leave the class and once again when they return. A total of two (2) responses will be submitted for each student.
I want to create a formula that will combine these two responses and show me the elapsed time between them - effectively giving me the time they were out of class.
Any help will be appreciated.
I created a spreadsheet with sample data and desired results to help show what I am looking at trying to create. There is also a sandbox-test sheet in there with some formulas I had some help with creating.
