2) It took more than 400 seconds for the child to travel from the first signpost to the second signpost
Statement A: We are not sure, Whether how much it takes for the travel- It may take 100 sec, 200 sec or even 300 sec- So Statement A is not sufficient.
Statement B: 800 meter(0.8 KM) takes less than 400. so we can say that this definitely did not take more than 400 sec- The answer to this statement is NO- Which is sufficient-

Since both the statements are given in the form of time, it is better to convert the question in the form of time. Distance = speed*time (125/60)*t>800? Or t > 384?
Statement 1: t < 450 Possible values of t: t < 384 384 < t <450 INSUFFICIENT
