I do not know how to find the acceleration!

The formulae are: v=u+at; s=ut+1/2at^2; v^2=u^2+2as;

where: v= final velocity, in ft/s,

u= initial velocity, in ft/s,

a= acceleration, in ft/s/s,

t= time in seconds.

Thanks in advance.

Can you find the average velocity of the train during the last minute?

Thanks for the quick reply, and that solves my problem

first find u given the contraints of the problem. Now you want to find the train's acceleration: what two pieces of information do you have in order to get the acceleration of the train? Think about assigning the distance from station A to B as a variable and using that in order to find the acceleration between the two points you know.
