These tasks: ΔV (change in the speed of the train under consideration when moving downhill) = 22.5 m / s; t (duration of movement) = 15 s.
The acceleration with which the considered train moved downhill is determined by the formula: a = ΔV / t.
Let’s calculate: a = 22.5 / 15 = 1.5 m / s2.
Answer: The acceleration of the train in question was 1.5 m / s2.
