To average 8 minutes and 15 seconds per mile, you would need to complete 1.84 miles in 15:10.8 There are 495 seconds in 8:15 (8*60+15)=495 seconds 495 seconds * 1.84 = 910.8 seconds 910.8/60 = 15 minutes with remainder of 10.8 seconds
A 15-year-old could run a 5K race in 30 to 45 minutes and this would be a good time. Running more often will shorten the time. A good time to be running a 5K race for a 15-year-old could be between 30 and 40 minutes. You can lower the time by running often and practicing.
An average eighth grader should be able to run the 100 meter dash in 15 to 16 seconds. Anywhere under 15 seconds is good and under 14 seconds is great!

Flight Time and Big Easy Won the Amazing Race in season 15! 2009!
it depends on the age group. 15 seconds is a decent time for a grade school 100 meter dash, but it would be a decent time for a high school 200 meter dash.
I am in high school and i was number 15 on the team when i ran a 23:33 in a 5k race. A good time to run it for a physical fit person would probablly be around there but if you arent in shape or are hurt, then a 25 or 26 minute 5k would be acceptable as well
11-13 seconds is a great time, but most girls run it in 14-16 seconds I'm 13 and I run it in about 11-12 seconds, I'm the fastest in my year but there are other girls from other school which are faster than me. Most of my friends run it in about 13-15+, so that's probably about average.
