The boat moves at a speed of 6 m / s, accelerates and in 2.5 s the speed will become 8.5 m / s. Find acceleration.

These tasks: V0 (speed of the boat before the start of acceleration) = 6 m / s; t (acceleration duration) = 2.5 s; V (speed of the boat after acceleration) = 8.5 m / s.
The acceleration with which the boat picked up speed can be expressed from the formula: V = V0 + a * t, whence a = (V – V0) / t.
Calculation: a = (8.5 – 6) / 2.5 = 2.5 / 2.5 = 1 m / s2.
Answer: During acceleration, the boat moved with an acceleration of 1 m / s2.
