• let whole distance is 'd' and speed of Alvin, Ben, and Clinton is A,B,C,,,
  then
  A*t=d .... 1
  B*t=(d-48).....2
  C*t=(d-72).....3
  so
  from eqt 1,2 & 3
  A:B:C::d:(d-48):(d-72).....4
  now second condition is..
  B:C::d:(d-32)....5
  froeqtn 4 and 5..
  (d-48)/(d-72)=d/(d-32)...
  on solving(or by option) d= 192...
