B...

This is one of those pain in the butt problems
Not hard, but you need to just calculate out the rate
If you aren't careful, this is one you can make a stupid mistake on..i.e. bad calculation

6miles = 5280*6 = 31680ft
1/2hour = 1800sec.

distance = time*spd

stmt 1. spd > 16 ft/sec
so, distance > 16*1800 = 28800
insuff.

stmt2. spd < 18 ft/sec
so, distance < 18*1800 = 32400
insuff.

stmt1+stmt2 28800 < distance < 32400 but, still insuff.

ans E

(E)..

6 miles = 6 * 5280 = 31680 ft.

I. speed > 16 .. minm distance = 16*1800 = 28800 .. we dont know whether its more than 31680 or not.

II. speed < 18, maxm = 18*1800 = 32400 ..dont know if thats more than 31680 or not..

Combining, it can be less than 31680 or more.. (note that spped can be real)..

from 1 i get

total distance > (16/5280)*3600/2 = 60/11

so 1 is not sufficient

from 2 i get

total distance < (18/5280)*3600/2 = 24.5.../4 which is greater than 6

so we have 60/11 < total distance < 6.something

E
