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 ---------------
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
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 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

A train initially stationary has a constant acceleration of 0.5 Miles per second what is the speed after fifteen seconds?
After 15 seconds, the train's speed would be 7.5 miles per second. This can be calculated by multiplying the acceleration (0.5 miles per second) by the time (15 seconds).
What is a car's acceleration if it increases its speed from 5 miles per second to 20 miles per second in 3 seconds?
The acceleration of the car can be calculated using the formula: acceleration = change in velocity / time. In this case, the change in velocity is 20 - 5 = 15 miles per second. So, the acceleration is 15 miles per second / 3 seconds = 5 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
A motorcycle can accelerate from 0 to 60 in 3 seconds what is its acceleration in miles per hour per second?
To calculate acceleration in miles per hour per second, first convert the acceleration from 0 to 60 mph in 3 seconds to miles per hour. 60 mph / 3 sec = 20 mph/sec. So, the acceleration in miles per hour per second is 20 mph/sec.
What is the acceleration between 7 miles per second to 2 miles per second in 5 seconds?
negative one mile per second per second
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
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.
How far does a plane fly in 15 seconds while its velocity is increasing from 75 miles per second to 145 miles per second at a uniform rate of acceleration?
To find the distance traveled, we can use the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. The initial velocity is 75 miles per second, the final velocity is 145 miles per second, and the time is 15 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time. Plug in the values to find the acceleration and then calculate the distance traveled in 15 seconds.
