The average velocity has two parts to it: The average speed and the average direction. The average speed is: (the distance you travel between 0 and 3 seconds) divided by (3). The average direction is: the direction from (the place where you started at 0 seconds) to (the place where you finished at 3 seconds).
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2
The acceleration cannot be determined with this information. The beginning and ending velocity needs to be known. You can determine her average velocity, however. average velocity = displacement/time = (9mi - 3mi)/3s = 6m/3s = 2m/s
Acceleration is measured in distance per unit timer per unit time, or in SI units this is usually m/s/s or m/s^2. If an object's velocity increases by 15 m/s in five seconds this is an average acceleration of: 15 m/s / 5 s = 3 m/s/s
Acceleration = -20 mi/h^2
Velocity at time 0 sec = 0m per sec Velocity at time 3 sec = 45m per sec Acceleration is 45/3 = 15m per sec if the acceleration is uniform
The average velocity for the first 3 seconds of a skydiver's free fall would depend on the initial speed, air resistance, and gravitational acceleration, but generally, it could be around 55-60 m/s.

Acceleration = -20 mi/h^2
The magnitude of acceleration during the first 3 seconds can be determined by calculating the change in velocity over that time period. By dividing this change in velocity by the time interval (3 seconds), you can find the average acceleration magnitude during that time.
So acceleration is an increase of speed every second. The increase of speed was 9miles/sec and this was over 3 seconds. Therefore there was an acceleration of 3 miles/second every second i.e. 3m/s2
It is impossible to determine acceleration simply from time and distance.
