0 votes 0 votes x R x -x is related to x by 0 min since relation is at most 20 min apart xRy == yRx this holds as at most x and y are seperated by 20 min . xRy,yRz but x is not related to z , there may be a time of 40 min seperation at most rajsh3kar answered May 11, 2017 rajsh3kar comment Share Follow See all 0 reply Please log in or register to add a comment.
