At 71 I walk a mile 14 min 17 sec and run a mile 11min 55 sec.
A 23-year old man should be able to run a mile is about 8 minutes. Most people should be able to walk a mile in about 20 minutes.
The answer depends on how fast the 11 year old walks.
Depends on how fast they are
I am a girl and ran a mile in 6:30.... but most should in about 7:50-8:45ish
It depends on how in shape they are.
