A car is traveling in a straight line along a highway at a speed of `20 m//s`. The driver steps on the gas pedal, and 3 seconds later, the car's speed is `32 m//s`. Find its average acceleration.

Explanation

To find the average acceleration of the car, we can use the formula for average acceleration, which is given by:

\[ \text{Average Acceleration} (a) = \frac{\Delta v}{\Delta t} \]

where:
- \(\Delta v\) is the change in velocity,
