A subway train has to travel a distance of 1800 m until it stops at the next station. The train starts from rest and accelerates at a rate of 1.60 m/s2 for 15.0 s. It then runs at a constant speed for some time and finally slows down at a rate of 4.0m/s2 until it stops at the next station. How long did it take to reach the next station?
