If the boat goes from 30 km/h to 50 km/h over the next 4 h, what is its acceleration? Please help me

The acceleration is 5km/h

Explanation:

Given

Initial Velocity (u) = 30km/h

Final Velocity (v) = 50km/h

Time (t) = 4h

Required

Determine the acceleration

This question will be answered using the first equation of motion;

Substitute values for u, v and t

Subtract 30 from both sides

Divide both sides by 4

Hence;

The acceleration is 5km/h

i think the answer would be reserve.
