Problem: A 75meter long train car accelerates uniformly from rest. The speed of the train is 18 m/s when the front of it is adjacent to a railway worker who is standing 180m from where the front of the train was when it began accelerating.

Part A: What is the speed of the train when it passes the railway work?

Can someone please explain what the heck is going on?
