Hi PJW/Peter,
I found a mistake in stopping calculations.
Deceleration time is supposed to be 38.89/a=78sec. hence
deceleration distance=78*19.45=1517m (because avg.speed is 19.45m/s), but calculation shows deceleration time as 19.45/a=39sec. so deceleration distance was the 759m instead of 1517m
what is the correct approach here?

could you please check my calculations?
Line to be covered in between pages is “Non-stopping train will cover the 1698m in 44 sec.”
