The average speed is 8 and 8/9 mph.
8.9 miles an hour.
The average speed for the entire trip is 9mph.
To find the average speed of the cyclist, we first determine the total distance traveled. The cyclist rides 45 km east and then returns 45 km home, making the total distance 90 km. The total time for the trip is 4 hours. Thus, the average speed is calculated as total distance divided by total time: 90 km / 4 h = 22.5 km/h.
Average Speed = Total Distance/Total TimeTotal Distance = x + x = 2xTotal Time = x/10 + x/8 = x (1/10 + 1/8) = x ( 4 + 5)/40 = 9x/40Speed = 2x/(9x/40) = (2x * 40)/9x = 80x/9x = 80/9 = 8.9

The cyclist's displacement is the straight-line distance from their starting point to their final position. After traveling 1 mile north and then 1 mile east, the cyclist is located at the coordinates (1 mile east, 1 mile north). Moving 1 mile south returns them to the same latitude as their starting point, resulting in a final position of 1 mile east of the starting point. Therefore, the displacement is 1 mile east.

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.
no it cannot be zero as the formula for average speed is total distance/total time . if we will come back to the starting point also then also there is distance covered . so it cannot be zero.
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.
Above average returns refer to investment gains that exceed the typical returns expected from a certain asset class or benchmark. For instance, if the average annual return for the stock market is 7%, an investment yielding 10% would be considered above average. Investors often seek above average returns to enhance their portfolio performance, but achieving them typically involves taking on higher risk or utilizing specific strategies.
