The answer is 3km as there is 9 secs between it and distance = time/3 and 9/3 =3 so distance =3
25 percent more = 125/100 = 5/4 of the regular allowance
answer: 5/4 of the regular allowance
1 - 1/3= 2/3
180(2/3)= 120
120 hikers did not camp overnight.
Hopefully, this helps!
I dont really know for certain, but if I had to guess, I would say answer choices B and D.
