Maths problem

So, train A leaves Cheltenham at 21:13, running 15 minutes late. It is predicted to call at University station eight minutes behind schedule, at 21:47 and then to arrive at Birmingham New Street on time, at 21:45.

a] What speed must it be travelling as it passes through Five Ways Station?
b] What kind of research are the boffins at Birmingham University doing?
