1km per hour is 1/3 of 3km per hour, so the answer is 1/3 of an hour or 20 minutes.
It would take ~6.67minutes to run 1km at 9kmh.
At an average of about 1km per 15 min. It would take about an hour to walk 4km
A good half an hour :) Since it takes on average 12 minutes to walk 1km, 2km would be 24 minutes so for 2.5km...30 minutes
one hour
It depends on the speed/acceleration.
Well the average fat person will walk a km in appox one hour, but if your fit and skinny like myself you'll be able to walk it in 12 minuets. No need to thank me.
It's imossible, because avarage speed of human walking is from 5km to 5.5km per hour, maximum one is about 6.5km per hour. If you walk with avarage speed (5km/h), it will take 12 minutes (for 1km=100000mm). If you walk with maximum speed (6.5km/h), it will take 11+ minutes (for 1km=100000mm)
For a normally fit and heathly person, about 10 minutes - you should be able to walk 3km in an hour, 1km in 20 minutes and so half a KM in about 10. If it's raining probably longer though
Well, honey, the average time for a person to walk 1km can vary depending on factors like age, fitness level, and terrain. But on average, a person walking at a moderate pace can cover 1km in about 10-12 minutes. Of course, if you're strolling along like you've got all the time in the world, it might take you a bit longer.

That depends on the speed of the car, for example if the car is travelling at 30kph, it will take 2 minutes to travel 1km.
