How long does it take to walk 350 meters?

An average walking speed is between five and six kilometers per hour.

At the bottom end of that scale then, we get:

5km/h = 5000m/3600s = 25m/18s

350m / (25m / 18s) = 252s

or four minutes and twelve seconds.

At the high end of that scale, we have:

6km/h = 6000m/3600s = 5m/3s

350m / (5m / 3s) = 210s

or three minutes and thirty seconds

So for someone to walk 350 meters at an average speed would take roughly between three and a half to four and a fifth minutes.
