To the mods this isnt a Q that appeard on the DAT!!!! i picked it up from somewhere 🙂 on the net

Ok my car has 5 tires, and i rotated em quite frequently so that each is used equally, I burn the 5 when I total my SUV in an accident [I was drunk and was studying for the DAT while driving]

so anywho: For how many miles had each been used:
Solutions:
a>30,000miles
b>24,000miles
c>18,000miles
d>20,000miles
e>19,200miles

I think the real question is, "What kind of car has 5 tires?"

That can't be the entire question, you must still be drunk

thats E if you drove the car exactly 96000 miles.....
but thats not said in the question

heres the exact question

18. The five tires that came with Steves new car were rotated frequently so that each tire was used exactly the same amount of time as the others. the tires were replaced when the odometer read 24,000 miles. For how man miles had each been used?
a>30,000miles
b>24,000miles
c>18,000miles
d>20,000miles
e>19,200miles

 

[Chga]

ok 96000/4 = 24000 since only 4 tires can run

 

[armorshell]

ok 96000/4 = 24000 since only 4 tires can run

Um, because the tires are being rotated evenly, each tire is only used an average of 4/5ths of the time.

Therefore the answer is E
