# Two cyclists 2

At the same time, two cyclists left the towns A and B at constant speeds. The first one going from town A to town B, and the second one from town B to town A. At one point of the trip they met. After they met, the first cyclist arrived at town B in 36min, the second cyclist arrived at town A in 25min. How long did it take for the first cyclist to reach the meeting point after leaving town A?
