Answer:
20s
Explanation:
Since A and B are moving in the same direction (+) and A is faster than B, in each second, A moves 10-5=5 m towards B.
Therefore speed of A towards B is 5 m/s.
Initially the distance between them is 100 m.
We know,
Speed=distance/time. Therefore, time=distance/speed.
time=100/5=20s
