6420.4 Meters a second on average.
If you divide the meters by the seconds, you get the average speed. But that would be in meters / second, not in meters per second squared, which is a unit of acceleration.
The S.I unit for velocity is meters per second (m s-1).
It is usually meters per second. But it can vary if that is not a suitable unit to use.
10 meters/second2 refers to an acceleration. It is the same as 10 (meters/second) / second, and means that every second, the speed changes by 10 meters/second.
.5 meters per second.
Just divide the distance by the time. The answer is in meters/second. If you want to convert that to the more commonly used kilometers/hour, multiply the number of meters/second by 3.6.
(1,000 meters/20 minutes) x (1 minute/60 seconds) = 5/6 meter per second
Average human walking speed is typically around 1.4 meters/second, so it would take about 17.86 seconds. At top walking speed, it would take ten seconds.
1.5 meters/second
(4 meters/second)(40 seconds) = 160 meters.
2 meters per second :)
Time = Distance/Speed = 200 m/2 ms-1 = 200/2 s = 100 seconds.
You can walk 1.3 miles in 10 minutes at 3.50 meters per second.
6.25 meters per second
12 meters per second
To get average speed, divide distance travelled by the time. The answer will be in meters/second. If you want to have your result in km/hour, multiply the number of meters/second by 3.6.
