Work rate problem

[selango]

Two people walked the same distance, one person's speed is between 25 and 45,and if he used 4 hours, the speed of another people is between 45 and 60,and if he used 2 hours, how long is the distance?
A.116
B.118
C.124
D.136
E.140

Can anyone arrive at exact answer.

The options are all integers, whereas the distance in a given interval could be a non-integer as well. At the same time, the wordings are also not perfect for GMAT.

Person 1 could have walked any distance between 100 and 180, whereas Person 2 could have walked any distance between 90 and 120. Both A and B are the possibilities but we cannot zero in to the exact figure for the distance.

Fairly ambiguous

[outreach]

is it A
A and B can both be the answer


A. 29 58
B 29.5 59
C 31 62
D 24 68
E 25 70

Clearly there is ambiguity whether the answer should be an integer or no. But if the answer is an integer then the answer is A,
B is eliminated since it gives the speed as a fraction.
C,D,E all show the speed to be greater than 60 km/hr when divided by 2 each.

yeah, you are right

[vamshiiitk]

Assume both the speeds are an integer.
if time is taken half for 2nd guy then v2(second person)=2*v1(first person)
then chances are (v1,v2)={(26,52),(27,54),(28,54),(29,58)} becoz the ranges are in between
distance could be 104,108,112,116
only 116 is there in choices

So Ans is A
