Which is the average acceleration during the time interval 0 seconds 10 seconds?

Average acceleration = (change in speed) / (time for the change)

In this case . . .

Average acceleration = (speed at the end - speed at the beginning)/10sec.

We can't be any more specific without knowing the difference
between the beginning speed and the ending speed. 

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds

The answer is a.  i hope this
