Answer:

Distance (d) given initial velocity (v0), final velocity (vf) , and time (t), assuming constant acceleration:

d=v0+vf2∗t

Given that the acceleration is constant:

Initial velocity is zero (because it starts at rest) → v0=0

Final velocity is 80 m/s → vf=80

Elapsed time is 20 s → t=20

Distance is unknown → solve for d

d=0+802∗20

d=800

Therefore, the distance traveled was 800 meters.
