∙ 12y agoaverage speed = S1+S2/2
here
s1 = 40kmph
s2 = 60kmph
Average speed = 40+60/2
100/2
= 50 kmph

∙ 12y agoEvery time the unicycle returns to its starting point, the average velocity equals zero. The total displacement divided by the time.
If the car has an average speed of 65 mph, when it returns to its starting point, it will have a displacement of zero and an average velocity of zero, because velocity has both speed and direction.
You can't calculate the average of 95 and 65 in this case - the answer will be slightly off. Instead, calculate the time the train took to go one way, and the time it took to go back. Then divide the total distance by the total time. This will give you the average SPEED. (Average VELOCITY will be zero, since the train gets back to its starting point.)
It actually can. Say a car moves north at 50 miles per hour for 4 hours. Then it moves south at 50 miles per hour for 4 hours. In the end, it returns to it's starting point. The average velocity over that 8 hour period is then zero, because it really went nowhere.
For calculating the market return, the average daily returns of S&P 500 or Nasdaq or any other Index (that represents a 'market') over the last few years (say 5 years) can be computed. These daily returns are then annualized (average daily return * 365). In Excel, you can download the daily closing prices of the index. Calculate daily returns of the Index using the formula (P1 / P0 - 1), (P2 / P1 - 1) and so on.... This will give you daily returns on the stock. Calculate the average of all the values (daily returns) obtained using "Average" function. Annualise the returns as (Average Daily Return * 365) You can get stock prices in Excel format with the spreadsheet in the related link. It automatically downloads historical prices from Yahoo Thanks Vikash

A simple example is a ball tossed into the air. When the ball reaches its apex -- its highest point -- its instantaneous velocity is zero. If we assume that up is the positive direction, the ball's velocity is positive when it is initially tossed into the air, but it slows immediately. That is, its velocity becomes less positive until it reaches zero velocity. After that point, the velocity becomes increasingly negative (because down is the negative direction). Until the ball returns to earth and reaches the height at which it was initially thrown, its average velocity is non-zero. If the ball is allowed to hit the ground, its average velocity will be slightly negative, which is still non-zero. But it still had an instant -- at its apex -- when its velocity was zero.
There is a great variety of websites dealing with average stack market returns. The easiest way to learn about average stack market returns online is to use your best judgement.
Never. The geometric return is always lower than the arithmetic average returns unless the returns for the given set of data are all the same.
