The first one is faster
The formula used to find the time it takes for an echo is: Time = 2 * distance / speed of sound. The speed of sound in air at room temperature is approximately 343 meters per second.
It could be anything from transmission speed sensor to just a broken speed cable.
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.

The repetition of sound caused by the reflection of sound waves is called an echo. It occurs when sound waves bounce off surfaces and return to the listener after a delay, creating a distinct repetition of the original sound.
It is the resistor, replace it.
The gauge maxes out at 120 mph and 112 is no problem.
You can use an echo to find out the speed of sound by timing how long it takes for the echo to return after making a loud noise. By measuring the distance between the source of the noise and the reflecting surface that created the echo, and timing how long it takes for the echo to return, you can calculate the speed of sound using the formula: speed of sound = distance traveled by the sound / time taken for the echo to return.
echo will not return output when using parenthesis because echo is not a function like print. echo is a language construct. The benefit to using echo over the print function is speed, plus you can separate data types using comma's rather than periods.Example:echo 'This is a string ' , $variable , ' ending string';is the same (but faster) as:print('This is a sting' . $variable . ' ending string');
