If my treadmill says speed 2.5, does that mean 2.5 miles per hour? How long will it take me to walk 3.1 miles

Answer 1

2.5 km/h is pretty slow, so I would think that 2.5 means mph. This is a fairly slow walk, and it will take you about 1:14 to do 3.1 miles.

Answer 2

Yes that does mean your speed

Avergely if you walk at 1 speed it will take an hour 2.5 speed would probably take 50 minutes it would take you about 2 and a half hours

Answer 3

It might do or it might be in kilometres.
Assuming it is in miles, then, walking at 2.5 mph, you would take approximately 75 minutes to walk 3.1 miles.
