I am given the speeds of eight objects, and I have to find the average speed and the RMS speed of these objects. I feel like it might have some relevance in terms of weighting in both cases but again, I do not know the masses of the objects. I tried assuming they all had the same mass and did not get the result I wanted.
Problem 1 :. A person travels from Newyork to Washington at the rate of 45 miles per hour and comes backs to the Newyork at the rate of 55 miles per hour. What is his average speed for the whole journey? Problem 2 :. A man takes 10 hours to go to a place and come back by walking both the ways.
