uniform acceleration. If it aquires a velocity
of 80 m/s in 20 seconds, find the distance
covered by it.

Answer:The acceleration is the derivative of the speed by the time.
Assuming the acceleration to be constant (and consequently the speed to increase linearly), then simply the rules of derivation lead to the acceleration being the division of the final speed by the duration of the acceleration.
Which would be 20/25 = 0.8 m/s²
