They are the same .
(4 meters/second)(40 seconds) = 160 meters.
2.7 meters per second is the same speed as 100 meters in 37 seconds. A person ... Usain Bolt ... has run 100 meters in 9.58 seconds. If, in the person's state of hyper-adrenaline-fueled terror, he can run only 1/4 as fast as Usain Bolt, then he can outrun that lava. Just barely.
You need to convert the minutes into seconds so that the units match. 1 minute = 60 seconds 20 minutes = 1200 seconds speed = distance travelled divided by the time taken so- speed = 1000m divided by 1200s speed = 8.333m/s
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.
Time = Distance/Speed = 200 m/2 ms-1 = 200/2 s = 100 seconds.
Someone traveling 10 meters in 5 seconds is moving at the same speed as the one going 20 meters in 10 seconds.
(4 meters/second)(40 seconds) = 160 meters.
my Friend is 5sec faster per 200 meters
(1,000 meters/20 minutes) x (1 minute/60 seconds) = 5/6 meter per second
.5 meters per second.
443/0.6 = 7381/3 seconds = 12 minutes 181/3 seconds

for a slow fat person it would take about 5 minutes, faster person would take 3 minutes
Well, you have to move much faster than 200 mph to be faster than the human eyes.LeClairity shared this bit of info a while ago:The question really is - can you move fast enough so that the eye won't perceive you. So, you don't have to move faster than the speed of light as some contributors suggest here - only fast enough so that you're moving faster than the eye's response time.Think about a movie - the frames are about 24 frames per second, and you can't perceive the flickering. That is for no perception of flicker - the perception limit is maybe around 100-300 Hz depending on person and conditions. So, maybe around a few millisec.So, lets say you are staring straight ahead, and a 0.25 meter wide person runs past. If they can move that 0.25 meter in 1 millisec, then they will effectively be "invisible". Or about 250 m/s. Then, by the time your eye catches up, the person has moved aready, so there is no overlap.and1 mile = 1609.344 meters1 hour = 3600 secondsFirst we find out how many meters per hour:(250 meters / 1 second) * (3600 seconds / 3600 seconds)900,000 meters seconds / 3600 seconds^2900,000 meters / 3600 seconds900,000 meters / 1 hourConvert our total meters into miles:900,000 meters * (1 mile / 1609.344 meters) = 559.235 milesTherefore 250 meters/sec = 559.235 miles/hourso if something moved at 559.235 miles/hour, or faster, it would be faster than your eye can perceive unless they saw it coming to or from, like a vehicle on a road or in the air.but a Person would be a flicker or less.. The main problem is that Mach 1 is 760 mph and something moving that fast causes a physical atmospheric disturbance. A loud one
This is really slow. World-class athletes can run this distance in 15 seconds. A person jogging can run this distance in about 50 seconds. Walking at a slow pace, a person should still be able to do this in about 180 seconds (3 minutes).
