Happy to do so, but obviously my response time depends upon my other committments.
Quite intrigued re the source of these exercises, as they are not IRSE material as far as I know. However they are very pertinent and discussion of them useful to many I am sure.

no worries, thanks for your comment and suggestion. I will move the signal is bit more back instead of 300m before the points. For the demarcation line shown on the layout, I will adjust it in line with my calculation.
"Given you have calculated that it takes 50m to accelerate up to 25km/h, then I think the length to be travelled at that constant speed would be 800 - 265 - 50 = 485m. Hence I basically agree with you but it wasn't obvious to me where you were getting the 440 value from, so a little further explanation would have been good."
I think I am wrong for this, I don't know why I put 440m on my calculation??. The final answer is 485m for sure.
thanks for reviewing my work
