To calculate speed using an echo, measure the time it takes for a sound wave to travel to an object and back. Divide the total distance by the time taken to get the speed. This method is commonly used in technologies like sonar and radar.
Please clarify what you want to calculate about the echo.
To calculate initial speed (also known as initial velocity), use the following formula: initial speed = (final speed - acceleration*time). You will need to know the final speed, acceleration, and time to calculate the initial speed accurately.
The time it takes for a sound to come back as an echo depends on the distance between the sound source and the reflecting surface. Sound travels at a speed of approximately 343 meters per second in air, so you can roughly calculate the time by dividing the total distance the sound travels (to the reflecting surface and back) by the speed of sound.
To calculate speed, you can use a simple formula: Speed = distance ÷ time. You can measure distance in meters or kilometers and time in seconds, minutes, or hours. This formula helps determine how fast an object is moving in a given direction.
To calculate the distance an object has traveled, multiply its speed by the time it has been traveling. This formula can be written as distance = speed * time. Make sure to use consistent units for speed and time when applying this calculation.
Please clarify what you want to calculate about the echo.
actually an echo does not have any speed . it travels at zero speed

You can use a graph to calculate speed.
To calculate average speed, you measure how long it takes(T) to get from point A to point B. Then you use the formula below: speed = (B - A)/T
If you want to be as accurate as possible you will need to start with the temperature of the air. Once you know the temperature of the air you plug it in to this formula: V = 331 √1 + (T/273) V is the velocity of sound in air at temperature T in degrees Celsius. Now that you know how fast sound will travel through the air at the current temperature, measure the time it takes for the sound to be transmitted and the echo received. Take that number and plug it in to this formula: V = m/s or Velocity = meters/seconds From that we get: Distance = Velocity/time Divide the distance in half and you have your distance from the object which the echo bounced off of.
Speed = Distrance / time
An echo sounder operates by measuring the time taken for a sound wave to travel from the device to an object on the seabed and back again. This time measurement is used to calculate the distance between the echo sounder and the object by utilizing the speed of sound in water.
To calculate initial speed (also known as initial velocity), use the following formula: initial speed = (final speed - acceleration*time). You will need to know the final speed, acceleration, and time to calculate the initial speed accurately.
The time it takes for a sound to come back as an echo depends on the distance between the sound source and the reflecting surface. Sound travels at a speed of approximately 343 meters per second in air, so you can roughly calculate the time by dividing the total distance the sound travels (to the reflecting surface and back) by the speed of sound.
Speed of light in water = speed of light in vacuum/refractive index of water
To determine the speed of your bike, you can use a bike computer or a GPS device that tracks your speed in real-time. Another method is to use a smartphone app that uses GPS to calculate your speed. You can also calculate your speed manually by measuring the distance you travel in a certain amount of time and then dividing that distance by the time taken.
