Train Acceleration Problem: Finding Final Car Velocity at 190m Distance

[confusedaboutphysics]

hey could someone tell me how to start this problem? i don't know which formula I'm suppose to use..

A 90 m long train begins uniform acceleration from rest. The front of the train has a speed of 19 m/s when it passes a railway worker who is standing 190 m from where the front of the train started. What will be the speed of the last car as it passes the worker?

is the velocity 19 m/s? and the distance is 190 m?

iS IT GIVEN that the train accelerates or deccelerates? if none of these , then velocity should remain same.

You need to calculate the rate of acceleration using the speed at 190 meters. Then calculate the speed at 190 + 90 = 280 meters by answering the question "how much additional speed will the train gain when it accelerates over 90 meters?"
