Leena can start 5 min after Guard check from point A and go for 50 min forward, she then returns for 5 min while the next guard checking. During return period the Guard would think Leena is coming from point B! After Guard check Leena is at 45 min distance from point A and can go for a further one hour to reach the point B.
