GMAT Prep?? (Pei Rate)......PLEASE HELP AGAIN!!!!!

by dferm » Fri Aug 08, 2008 5:43 am
Did it take Pei more than 2 hours to walk a distance of 10 miles along a certain trail? (1mile=1.6 Kilometers, rounded to the nearest tenth)

(1) Pei walked this distance at an average rate of less than 6.4 kilometers per hour

(2) On average, it took Pei more than 9 minutes per Kilometers to walk this distance.

Can someone please shed some light on this Problem?

Thanks.

Clue #2: is confusing me.....

10 Miles = 1.6 * 10 = 16km

Lets see statement 1 : on an average the speed is less than 6.4 Km/hr. So in 2 hours the maximum distance travelled is 6.4*2 = 12.8 km. 12.8 is less than 16 km. So with statement 1 itself we can nswer this question.

Lets see statement 2 : it takes 9 minutes to travel 1 km. so in order to travel 16km it will take 16*9 = 144 minutes = 2 hours 24 minutes. It is more than 2 hours.

So both statement answers the question independently.
Answer: D
