Distance>100 km & R>60 > is t>2?
st1. D<120 > (<120)/(>60)=<2 therefore sufficient. st2. R<80 > (>100)/(<80)= !2 . could be greater or less than 2. therefore insufficient.

At 11 AM, Abraham leaves from his home for a meeting that is scheduled for 1 PM. If the venue of the meeting is not less than 100 kilometers away and Abraham drives at a speed not less than 60 kilometers per hour, will he be late for the meeting?
Rephrase the question: Is d/s<= 2
(1) The venue of the meeting is less than 120 kilometers away
Test the threshold
Let d=100 & S=60..........100/60= 1 2/3 hr < 2
Let d=120 & S=60..........120/60=2 hrs
This means that if we increase the distance to be not less than 60, then the time required will be always less than 2 hrs. So he will catch up his meeting,
Sufficient
(2) He does not drive at a speed greater than 80 kilometers per hour
Let d=160 & S=80.........160/80=2 hrs .........arrive on time
Let d= 320 & S=80.........320/80=4 hrs ........arrive late
Insufficient
Answer: A

Hey, PFB the official solution. Steps 1 & 2: Understand Question and Draw Inferences• Let Distance between home and meeting venue = D kilometers • Let Speed of driving be S kilometers per hour • Let time taken = T hours To Find: Is \(T > 2 hours\)? • \(Time = \frac{Distance}{Speed}\)
o \(T_{min} = \frac{D_{min}}{S_{max}}\)
o \(T_{max} =\frac{D_{max}}{S_{min}}\) If: o \(T_{min} > 2\) hours, then the answer is NO
o If \(T_{max} < 2\) hours, then the answer is YES.
o If \(T_{min} < 2 < T_{max}\), then a definite answer cannot be determined Step 3: Analyze Statement 1 independentlyStatement 1 says that \(D_{max} < 120\) km So, \(T_{max} < \frac{120}{60}\) hours That is, \(T_{max} < 2\)hours Sufficient to answer the question (he will reach the venue in time) Step 4: Analyze Statement 2 independentlyStatement 2 says that \(S_{max} = 80\) kmph This means, \(T_{min} = \frac{100}{80} =\frac{5}{4}\) hours So,\(T_{min} = 1\) hour \(15\) minutes But we don’t know about the maximum time he’ll take. So, not sufficient.Answer: AThanks, Saquib Quant Expert eGMATRegister for our Free Session on Number Properties (held every 3rd week) to solve exciting 700+ Level Questions in a classroom environment under the realtime guidance of our Experts
