1000 DS section 1- Q-15

by ash_maverick » Sat Jun 06, 2009 9:52 pm
On a certain day it took Bill three times as long to drive from home to work as it took Sue to drive from home to work. How many kilometers did Bill drive from home to work?
(1) Sue drove 10 kilometers from home to work, and the ratio of distance driven from home to work time to drive from home to work was the same for Bill and Sue that day.
(2) The ratio of distance driven from home to work time to drive from home to work for Sue that day was 64 kilometers per hour.


Unable to understand "and the ratio of distance driven from home to work time to drive from home to work"

I think language says the ratio of distance and time for each person..

SO IMO A is the sufficent

Db = Distance travelled by Bill
Tb= time taken by bill

SO Db/Tb = Ss/Ts

Ss = 10 and Tb=3Ts thus we can find Db...

So A is the answer

But B is insufficient...

You are right nervesofstee. Now i read the first statement carefully and found that it says the ratio of distance/time. Thanks for your quik response.
