1km per hour is 1/3 of 3km per hour, so the answer is 1/3 of an hour or 20 minutes.
3km is always 3km it makes no difference if you run or walk
3 hours.
10 minutes on average
It depends at what speed you drive
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
At 3 kph, it will take one hour. At 30 kph, it will take six minutes.
By unit of length and distance and conversion ,we can say that 1 km=1000 m 3km=3000 m
About 3km- and about 5 times a week.
depends on how fast you walk
3km = 300,000
It depends on how fast you are walking, if you are walking at 6km/h then it will take you an hour to walk 6km. if you are walking at 3km/h then it will take you 2 hours.
