### Adding Standard Number to Time?

I want to start off by saying I never even knew of this program before today and have no experience. I would like to build this app for my use but I am getting stuck while trying to add a number to a time and I am unsure how to proceed.

I am trying to find the time you should arrive at point B from point A.

So far I have Miles * 60 / Speed = Minutes to arrive.

I would like to add Start Time + Minutes to arrive = Arrival Time.

The issue I have is figuring out a way to show the Arrival Time.

So if my miles are 10.3 and my speed is 12 and my Start time is 11:07 I want my Arrival time to show 11:58.

Miles * 60 / Speed = Minutes
Then
Start Time + Minutes = Arrival Time

Is there a way to get the number to add to a time and show the new time?

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook   http://www.appinventor.org/book2 ... the links are at the bottom of the Web page.  The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro  and the aia files for the projects in the book are here:  http://www.appinventor.org/bookFiles
How to do a lot of basic things with App Inventor are described here:  http://www.appinventor.org/content/howDoYou/eventHandling  .

Also do the tutorials http://appinventor.mit.edu/explore/ai2/tutorials.html to learn the basics of App Inventor, then try something and follow the

You will not find a tutorial, which does exactly what you are looking for. But doing the tutorials (not only reading a little bit) help you to understand, how things are working. This is important and this is the first step to do.

I am not using the current time for adding minutes, it is an inputted time. So if it is currently 10am and I am leaving at 11:16am I need to know what my arrival time is prior to the leaving time.

The Clock component is in the Designer's Sensors drawer.
Pull it in to the project anyway.
It has lots of time conversion, formatting, and manipulation blocks.
