question/help please?
My son has a walk a thon today from 845 to 1130am can't wait but am sure the pace will be slow do you think counting it as 2.5 mph would be accurate to count? Or do you think 2.0 mph? I'm not sure but I want to be as close to accurate as i can be. I'll use my stop watch for actual time and they are first graders if that…
