actually yes they can
A 10k run is approximately 10,000 meters in distance.
It's perfectly OK to walk in most 10k races (although more people will be running than walking), especially if the race is titled "10k run/walk." However, if it's specifically called a "10k run," you might want to email the race organizers and ask if it's OK to walk. Sometimes a race has a "5k run/walk" and a "10k run," meaning that you can run and/or walk in the 5k but can only run in the 10k. Basically, it's most likely that walking is totally fine. It's not like they can disqualify you for walking, anyway.
That depends on how long you have been training for. I am 46 and run 10k or 6.2 miles on average 40 mins each time. hope that helps, training is the key to improving.

10 Kilometers!
10k
a big no
It would take 1 hour and 15 minutes to run 10k at a pace of 8k per hour.
Human beings cannot run 44.172 km per hour (yet). However, if they could, it would take 13.6 minutes to run a 10k.
It depends on the speed at which the runner is travelling.
