Usain Bolt in the 100m final last night averaged about 23.23 mph (≈ 37.38 km/h) for those 9.63 seconds - his peak speed would have been slightly over that.

5 min 20 sec = 16/3 min per mileSo she runs at 3/16 miles per minute = 60*3/16 miles per hour = 11.25 miles.However, it is unlikely that any runner can maintain their 5-minute pace for an hour.5 min 20 sec = 16/3 min per mileSo she runs at 3/16 miles per minute = 60*3/16 miles per hour = 11.25 miles.However, it is unlikely that any runner can maintain their 5-minute pace for an hour.5 min 20 sec = 16/3 min per mileSo she runs at 3/16 miles per minute = 60*3/16 miles per hour = 11.25 miles.However, it is unlikely that any runner can maintain their 5-minute pace for an hour.5 min 20 sec = 16/3 min per mileSo she runs at 3/16 miles per minute = 60*3/16 miles per hour = 11.25 miles.However, it is unlikely that any runner can maintain their 5-minute pace for an hour.
The runner would be running at 6.67 miles per hour. This is answered by dividing 60 (minutes in an hour) by 9 (minutes it took for one mile). You are basically saying that the runner will run a mile every 9 minutes, so how many '9 minutes' (each mile ran) are in an hour.
141.672 miles an hour
55 kilometers an hour=34.1754156 miles per hour
3 hours
The answer depends on the distance for the race. A marathon runner could not maintain the speed attained by a sprint runner.

It will take him two (1.98) minutes.

It will take 4 hours, provided the runner can maintain that speed.
