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 .
The time it takes to cross the street at a normal walking pace depends on the width of the street. On average, a person walks at about 3 to 4 miles per hour, which translates to approximately 1.33 to 1.78 meters per second. If the street is around 10 meters wide, it would take roughly 6 to 8 seconds to cross.
.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.
The time it takes to walk 25 meters would depend on the individual's walking speed. On average, a person walks at a speed of about 1.4 meters per second, so it would take approximately 17.9 seconds to walk 25 meters. Factors such as terrain, incline, and physical condition can also affect the time it takes to cover this distance.
The time it takes to walk 30 meters can vary depending on walking speed. On average, a person walks at a speed of about 1.4 meters per second. Therefore, it would take approximately 20 seconds to walk 30 meters at a typical walking pace.
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
Someone traveling 10 meters in 5 seconds is moving at the same speed as the one going 20 meters in 10 seconds.
Time = Distance/Speed = 200 m/2 ms-1 = 200/2 s = 100 seconds.
They are the same .
D. the person is walking away at a constant velocity
