How many seconds is 340 meters per second?

340 meters per second is a measure of speed, not a duration of time. To find out how long it takes to travel a specific distance at that speed, you would need to define the distance in meters. For example, if you wanted to know how long it takes to travel 340 meters at that speed, it would take 1 second, as speed is distance divided by time.


What is the unit of the slope of the speed-time graph?

The slope represents acceleration. Assuming standard SI units (if the speed is in meters/second, and the time in seconds), the slope would represent meters/second2.


How long is 200 meters in minutes on a treadmill?

The time it takes to cover 200 meters on a treadmill depends on the speed at which you're running or walking. For example, if you are running at a speed of 10 km/h (which is roughly 2.78 meters per second), it would take about 72 seconds, or 1.2 minutes, to cover that distance. If you walk at a speed of 5 km/h (about 1.39 meters per second), it would take approximately 143 seconds, or about 2.4 minutes. Adjust your time based on your specific speed.


How long to walk 450 meters in minutes?

The time it takes to walk 450 meters will depend on the individual's walking speed. On average, a person walks at a speed of about 1.4 meters per second, which is equivalent to 84 meters per minute. Therefore, to walk 450 meters at this average speed, it would take approximately 5.36 minutes.


What is a runners average speed if he runs 100 meters in 15 seconds?

To calculate the runner's average speed, you would use the formula: speed = distance ÷ time. In this case, the distance is 100 meters and the time is 15 seconds. Therefore, the average speed of the runner would be 100 meters ÷ 15 seconds = 6.67 meters per second.

How long would it take to walk 25 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.


How long does it take to travel 425 meters?

The time it takes to travel 425 meters depends on the speed at which you are traveling. For example, if you are running at a speed of 5 meters per second, it would take you 85 seconds to travel 425 meters.


How much time does it take to walk 256 meters?

Assuming each meter takes between 1-3 second, depending on the step size and the speed of a person, 256 meter would take between 256 to 768 seconds. Meaning it approximately takes between 4 to 12 minutes to walk 256 meter.


What is the frequency of a sound wave with a wavelength of 0.1 meters?

The frequency of a sound wave with a wavelength of 0.1 meters can be calculated using the formula: frequency = speed of sound / wavelength. Assuming the speed of sound is 343 m/s (at room temperature), the frequency would be 3430 Hz.


What is the wavelength of a 25hz sine wave?

The wavelength of a 25Hz sine wave can be calculated using the formula: wavelength = speed of sound / frequency. Assuming the speed of sound is approximately 343 meters per second, the wavelength of a 25Hz sine wave would be around 13.72 meters.


How long would it take to walk 150 meters?

This depends on the speed of your walk. The conventional method is time consuming to walk 2.5 minutes.


How many seconds are in a mile?

There are 5,280 feet in a mile, and since 1 foot is approximately 0.3048 meters, a mile is approximately 1,609 meters. Assuming a running speed of 6 meters per second, it would take roughly 268 seconds to run a mile.


If a sound has a wavelength of 2 meters What is its frequency?

The frequency of the sound wave would be the speed of sound divided by the wavelength. Assuming we're in air at room temperature, the speed of sound is approximately 343 meters per second. Therefore, the frequency would be 343 m/s / 2 m = 171.5 Hz.


How do you spell out 2.2 m?
