A train going from one station to the next on a straight section of track accelerates from rest at 1.4m/s^2 for 15s. It then proceeds at constant speed for 1100m before slowing down at 2.2m/s^2 until it stops at the station. What is the distance between the stations? How long does it take the train to go between stations?

figure the distances during the acceleration, and the final velocity.
Then figure out the distance to deaccelerate. 
o...i got that, but what formula do u use to find the time it takes to go between stations?
