Ali and Faizer are 27m apart. They both start walking and meet 9 hrs later. If they travel in the same direction and meet after 3 hrs, faizer’s speed must most likely be :

a)3mph b)9mph c)6mph

• A)3MPH
  let, speed of Ali=X mph and Faizer=Y mph
  Now, relative speed when Ali is walking int the same direction with Faizer= (X-Y)mph
  hence, according to question, 27/(X-Y)=9 ; solving X-Y=3; --- 1
  Now relative speed when walking in the opposite direction= (X+Y) mph
  ATQ, 27/(X+y)=3; solving X+Y=9; --- 2
  solving 1 and 2 we get X=6 and Y=3, where Y is the speed of Faizer.
