Depends on what you mean by untrained. I think most men who exercise regularly and don't carry a ton of extra bodyweight, even with zero running, could bang out 1.5 miles at 9:40 pace. Couch potatoes, no.
I don't think many people who don't exercise running can do 1.5 miles in 9:40.
Any other sport? Cycling, swimming, rowing, ball sports, team sports, weightlifting, ...

It's 1.5 miles at 9:40 mile pace; 14.5 minutes total. Much easier than 6:30 pace (what you're imagining).
