Answer is A
In 5 mins he could cover 250 meters. Hence he is 50 m/mins faster. So it will take 2 mins

(1) 5 minutes ago, cyclist A was 200 meters behind cyclist B.
(2) Cyclist A is moving 25% faster than cyclist B.


The question basically asks the relative speed of A wrt B. This means that we don't need to find the individual speed of A & B


Statement 1
In 5 minutes A cycled 250 m more than the distance traveled by B.
In other words, Relative Speed of A is = 250/5 = 50m/min
Time to cover extra 100 m will be 2 Min
Thus Sufficient.

Statement 2
In 5 minutes A cycled 250 m more than the distance traveled by B.
Speed of A is 25% more than B's.
This option will give different answers depending on the speed of B.
Thus Insufficient.

Answer A

Two cyclists are racing up a mountain at different constant rates. Cyclist A is now 50 meters ahead of cyclist B. How many minutes from now will cyclist A be 150 meters ahead of cyclist B?

(1) 5 minutes ago, cyclist A was 200 meters behind cyclist B. In 5 minutes A gained 200+50=250 meters --> 50 meters in 1 minute. To gain additional 100 meters he'll need 2 more minutes. Sufficient.

(2) Cyclist A is moving 25% faster than cyclist B. If both cyclist are very slow A'll need more minutes than if both cyclist are very fast. Not sufficient.

Answer: A.

I marked C but i do realize my mistake now . still sorry guys not able to understand your explanation 700+ problms distance/rate kills me

i was able to form the answer in some other way ;

let x be the distance travlled by B in those 5 min in which x got ahead .
Speed of A = A , Speed of B=B

distance travlled by A will 200m + 50m + x(distance by B ) = A * 5min ------ 1

distance by B = X = B * 5 min ------2

Subtract 2 from 1

250 + X - X = 5(A-B)

250/(A-B)=5min

so 250 distance will be covered in 5 min
so 150 can be done in 3 min
