A people walked from signpost 1 to signpost 2 at the average rate of 0.125km/m. Is the distance between two signposts greater than 0.8km?
1). It cost more than 400 second for the people finish the trip
2). It cost less than 450 second for the people finish the trip.

[spoiler]IMO A?[/spoiler]

1) since speed is 0.125 km/m, and time taken is atleast 400 seconds.
total distance will be atleast 0.125*400/60 = 5/6 which is greater than 0.8. hence suff.

2) since time taken is less than 450 seconds. we know the distance can be or may not be greater than 0.8. hence insuff.
