pretty sure its 180....
this is how i did it...
first calculate all of sam's distance... so it will be the total of 365. and then u subtract 10 because sam drove 10 MORE miles so for tim it will be 10 LESS miles. after that it will be 355. and THEN you need to subtract 175 to find the distance from liverpool to bristol.
ALSO. IF YOU STILL DONT UNDERSTAND PLEASE TELL ME I WILL SEND U A PICTURE OF THE WORK INSTEAD :D
happy to help!
