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.
(4 meters/second)(40 seconds) = 160 meters.
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
Time = Distance/Speed = 200 m/2 ms-1 = 200/2 s = 100 seconds.
They are the same .
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.
.5 meters per second.
(1,000 meters/20 minutes) x (1 minute/60 seconds) = 5/6 meter per second
the person is walking at a constant velocity
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).
(4 meters/second)(40 seconds) = 160 meters.

D. the person is walking away at a constant velocity
Basically velocity is speed in a specific direction. So just the speed of the person when waking in the wind with a specific direction.
the person is decreasing resultant velocity
Someone traveling 10 meters in 5 seconds is moving at the same speed as the one going 20 meters in 10 seconds.
