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.

(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 & BStatement 1In 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 2In 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
