My task is to "display the words: 'The ball hits the ground at a distance of X meters', where X is the hitDistance from the function throwBallFunc." (I have written the throwBallFunc).
So far, I have disp( ' The ball hits the ground at a distance of %d meters '); which is not working. How do I write it so that I can get the value of X aka hitDistance from the function throwBallFunc that I created? Thank you!

Use:
sprintf( ' The ball hits the ground at a distance of %d meters ',X)
or:
fprintf( ' The ball hits the ground at a distance of %d meters ', X)
instead, depending on what you want to do.

I have to use the disp function. Any way I can do it with that?

Yopu didn’t say that.
Try this:
disp([' The ball hits the ground at a distance of ' num2str(X) ' meters '])
That worked when I tested it. It uses the MATLAB concatenation operator [] to create one character array from three character arrays.
