A bullet train traveling at 2.5m/s, takes 30 minutes to get to the station. What was the train's acceleration in m/s^2?

Explanation:

Given that,

Initial speed of a train, u = 2.5 m/s

Finally, it reaches the station, v = 0 (at rest)

Time, t = 30 minutes = 1800 s

Acceleration is equal to the rate of change of velocity. So,

So, its acceleration is .

i think it would be 80 km/h because 30 + 50 = 80 (sorry if this not the right answer i'm trying my best)
