Hey again,
Just curious about sumthing when I do HIIT on my Workout days I do 10minutes with 1min 4mph walking and 30sec 9mph sprint. I get about 1mile of distance when I do it. Now if I just 6mph at a steady pace for 10minutes i also get 1mile in distance.

Does this mean that doing 10min at 6mph is the same as my HIIT program?

Short answer, No. HIIT increases your heart rate so that you continue to burn calories/fat long after the work out is over. You will not get that spike when jogging at level 6 for ten minutes.
