Wave speed = frequency * wavelength
Rearrange so it's equal to wavelength. Do this by diving both sides by frequency to leave you with:
Wave speed / frequency = wavelength
340 / 265 = 1.2830 m
To find the average of something you must first add everything together and then divide it by the total amount of numbers you added together.
First add 72 and 64 together
72+64=136
Now divide 136 by 2
136/2=68
So the average speed of the train is 68 kilometers

Answer:
possible answer from edge
Explanation:
After World War II the only coal available to burn residentially, either for cooking or warmth, was of poor quality and contained large amounts of contaminants that made its fumes toxic. So when millions of homes in London burned this low quality coal and the local atmosphere over and around London stagnated, there was nowhere for the fumes to go. This stagnation allowed the toxic coal fumes to build up until they became physically harmful to humans and animals.
