# Problem P. 3983. (May 2007)

**P. 3983.** A racewalker on the training walked between point *A* and point *B*. First he walked from *A *to *B* taking 120 steps in each minute then he turned back at *B* and went back to *A* taking 90 steps in each minute. He turned back at *A* and went to *B* again and took 60 steps per minute, and finally he turned back at *B* and stepped only 45 in one minute until he got back to *A*. It took him 1 hour and 3 minutes. What is the distance in steps between the points *A* and *B*? What is the average steps that the walker took in one minute?
