Text: The crossing between Cambridge to Edinburgh takes around 8 hours...

[Flexmat]

Dear Peter and John,
Thanks for your last letter.Sorry, I haven't written you for a long time because
I had some difficulties to find the information about the price of the round-trip tickets of trains.
The crossing between Cambridge to Edinburgh takes around 8 hrs by car, 11 hrs by coach and only 5 hrs by train.
The best way of travelling to Edinburgh is to take train.Indeed,it's more comfortable than coach and quicker.But the
price is dearer $90 by train and $60 by coach(only on Friday and Saturday).To solve this problem,we can go on trip
on Monday because it permit to reduce the price:it's only $75!To be not tired we can leave at 07.56 am of Cambridge.
Well,that's all for now.I'm looking forward to hearing from you.
