You haven't mentioned distances or speed or acceleration, so this cannot be answered.
342 yards per second.
Assuming the same average rate of travel, since 100 yards is 0.9144 times the size of 100 metres, 10.8 seconds for 100 metres would correspond to 10.8 x 0.9144 = 9.87552 seconds for the 100 yards.
To find the unit rate, divide the total distance by the total time. In this case, 2736 yards divided by 8 seconds equals 342 yards per second. Therefore, the unit rate is 342 yards per second.
20 minutes
None. 2.5 seconds is a period of time. It is not a speed since there is no measure of distance involved. By contrast, yards per minte is a measure of speed. The two measures are incompatible.
5 seconds each blink!
increase tranfer rate and decrease average access time
Payback is usually a specified amount at a specified time. If money is to be gained at an average rate of return, the amount of the return could fluctuate due to inflation or interest rates.
rate x time = distance rate = distance / time rate = 500/25 Rate=20 meters per second
The average rate of movement, for example the number of feet traveled in a certain number of seconds, or the number of miles traveled in a certain length of time.
If he started out from "rest" (zero speed), then his average acceleration for the 5 seconds is50/5 = 10 meters per second2
The optimum online download rate is 12 seconds. 12 seconds is very good.
