2 miles an hour
The average speed is exactly 2 km per 30 minutes. In more popular units, it's 4 km per hour.
Average speed = 10 meters per 2 seconds.Other ways of stating it:-- 5 meters per second-- 18 kilometers per hour
4 kilometres per hour.
An average adult walks at the speed of 80m/min. So if you divide 1000m by 80m it gives you 12.5 minutes to walk 1 km.

The time it takes to walk 450 meters will depend on the individual's walking speed. On average, a person walks at a speed of about 1.4 meters per second, which is equivalent to 84 meters per minute. Therefore, to walk 450 meters at this average speed, it would take approximately 5.36 minutes.
Total distance is 1.4 km = 1400 m, total time is 20.2 minutes = 1212 seconds. Average speed = 1.155 m/s. Or is this a catch question to see if you understand the difference between speed and velocity? Velocity has a direction as well as a speed, this is called a vector quantity, and since you come back to the starting point, the average velocity is in fact zero. Note that I originally said speed is 1.155 m/s, not velocity.
To calculate average speed, divide the total distance by the total time taken. In this case, the student walks 10 meters in 2 seconds. Therefore, the average speed is 10 m / 2 s = 5 m/s.
Assuming the average person walks about 5 km per hour, then it would take roughly 6-7 hours to walk 30 km. Of course, that assumes no breaks or deviations from the path. Someone who is very fit could cover the ground faster.
The total displacement is 0 km, as the student returns to the starting point. The total time taken is 5 minutes + 7.1 minutes = 12.1 minutes. Therefore, the average velocity is 0 km divided by 12.1 minutes, which equals 0 km/min.
The average adult walks at about 4 miles an hour - so, two hours, or 120 minutes.
The time it takes to walk 1.71 miles depends on your walking speed. On average, a person walks at a speed of about 3 to 4 miles per hour. At this pace, it would take approximately 25 to 34 minutes to walk 1.71 miles.
