Explanation:

Answer 2

Your answer is:

1A] When A starts his journey at 4 sec , B has has already covered a distance of 857m.

B] A travels fatser than B because A starts his journey late but crosses B and covers more distance.

C] Speed of A=Distance/timeAt t=12min, distance covered=3500m=3500/12=375m/min

D] Speed of B=3000/12=214m/min

E] Speed of approach of A towards B=375m/min -214 m/min=161 m/min

F] Speed of seperation of A from B=161m/min.
