1. Convert time to seconds:
* There are 60 seconds in a minute, so 4 minutes is equal to 4 * 60 = 240 seconds.
2. Use the formula for speed:
* Speed = Distance / Time
3. Plug in the values:
* Speed = 40 meters / 240 seconds
4. Calculate the speed:
* Speed = 0.167 meters per second
Therefore, the speed of the wave is 0.167 meters per second.
