Hi, my first post

dont know if im on the right one :S.

Can someone help with this maths question, currently using SUVAT method.

A train leaves a station from rest with a constant acceleration of 0.3ms-1. It reaches its maximum speed after 90 seconds and mantains this speed for a futher 5 minutes, when it slows down to a stop at a second station with an acceleration of -1ms-2. How far apart are the two station.

Ive figured that the first 90 seconds its travelled 1215m I think. Can anyone help me with the rest. If you could to explain how you did it. I want to understand. Thankyou.
