The formula is C/T, where C is the change, and T is the time to take this change.
Thus, we can plug in the values as such: 25/30 = 5/6
(0.8(3)) is also a proper answer.

How to find magnitude of acceleration?
Rule: Magnitude of acceleration = Change of velocity / Time interval In linear motion, magnitude of acceleration is the measurement of change in speed in speed per unit time. For example: A car reaches a speed of 20 miles per second in 4 seconds, the magnitude of acceleration is 5 miles per second. a = 20 miles/second divided by 4 seconds = 5 miles per second. Acceleration is a vector, which means it has magnitude and direction. To describe accelerated motion completely, the direction also needs to be included. So it would be 5 miles per second in whatever direction it is going.
What is the acceleration of a car that goes from 32 miles per second to 96 miles per second in 8 seconds?
Acceleration = change in velocity/change in time Acceleration = 96 miles per second - 32 miles per second/8 seconds = 8 miles per second per second or, better expressed 8 mi/s^2 ---------------
When a runner accelerates from 0 miles per second to 3 miles per second in 12 seconds what was the acceleration?
3 / 12 = 0.25 miles/second2.
What is the acceleration in miles per second squared if a car is traveling 20 miles per second and takes 3 seconds to brake?
-6.667 miles per second squared
What is the acceleration of a car that goes form 0 miles per second to 25 miles per second in 3 seconds?
Acceleration = (change in speed) divided by (time for the change)Acceleration = (25 - 0)/(3) = 81/3 miles per second2Don't try this at home. That acceleration is about 1,368 G's. You can not survive it!
What magnitude is the acceleration from 54 miles per second to 4 miles per second in 0.75 seconds?
-66.667 miles per second squared

What is the acceleration of 3 miles per second to 9 miles per second in 3 seconds?
A gain of 2 miles per second squared
If starting on a skateboard and 10 seconds later traveling 20miles per second what is acceleration?
20 miles per second / 10 seconds = 2 miles per second ^ 2
What is the acceleration between 7 miles per second to 2 miles per second in 5 seconds?
negative one mile per second per second
When a runner accelerates from 0 miles per second to 3 miles per second in 12 seconds what was the acceleration?
3 / 12 = 0.25 miles/second2.
What is the acceleration in miles per second squared if a car is traveling 20 miles per second and takes 3 seconds to brake?
-6.667 miles per second squared
What is a car's acceleration if it increases its speed from 5 miles per second to 20 miles per second in 3 seconds?
5 m/s2
A motorcycle can accelerate from 0 to 60 in 3 seconds what is its acceleration in miles per hour per second?
20 miles/hour/second The acceleration is simple division 60/3 = 20.

A car accelerates to pass a truck going from 20miles per second to 29miles per second in 3 seconds what was the acceleration?
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
