Use the formula:
Speed = distance / time.
If you divide meters / seconds, the speed will obviously be in meters/second.
If you traveled 100 meters in 30 seconds, then you would be traveling at 3.333... meters per second, or 200 meters per minute, or 12 kilometers per hour (7.45 miles/hour).
Taking 10 seconds to move 500M would be, ummm, lets see, carry the one, times pi, ummm OH! It would be a speed of 50 meters per second, or 50m/sec That would be whipping right along!
B: "You are running very fast". "You run very fast" and "I can run very fast" are statements but neither indicates that you or I are currently running fast (we may well be, but the sentences do not convey that fact).
This is a pretty silly question. The most basic / fundamental answer is: "It depends on how fast you are travelling." If you are travelling at 400 meters per second (a slow-to-moderate speed bullet) then it will take only one and "a fraction of one" seconds. If you are walking (steadily) at 4 meters every second, it will take 110-1/4 seconds, or one minute and 50-1/4 seconds. Distance = Speed x Time ... thus, Time = Distance / Speed
Without any units for either the 40 or the 4.9 , the only thing we can say for sureis that your speed is exactly 40/4.9 , or about 8.163 length unit/time unit .-- If the 40 is meters and the 4.9 is seconds, thenyour speed is about 29.4 km/hr or 18.26 mph.-- If the 40 is yards and the 4.9 is seconds, thenyour speed is about 16.7 mph or 26.9 km/hr .
Running 100 meters in 12.5 seconds is equivalent to running at a speed of 22.4 miles per hour.
You would not be running at all.You would be travelling @ 0.245817 mph.
1000 meters in 60.6 seconds = 36.91 mph
900 meters/30 seconds = 30 meters/second
Your average speed is about 11 miles per hour.
To find the speed of runners who cover 40 meters in 8 seconds, you can use the formula for speed: speed = distance/time. In this case, the speed would be 40 meters divided by 8 seconds, which equals 5 meters per second. Therefore, the runners are running at a speed of 5 m/s.
6 seconds
98.63mph
2.5 seconds
0.57 seconds
both are just as fast although the one going 10 meters in five seconds is probably accelerating faster...
13 mph
