Three elephents A, B and C are moving along a straight line with constant speed in same direction as shown in figure. Speed of A is `5 m//s` and speed of C is `10 m//s`. Initially separation between A & B is 'd' and between B & C is also d. when 'B' catches 'C' separation between A & C becomes 3d. then the speed of B will be
