The distance to the telephone is 60 meters. This can be determined by first calculating the time it took him to get to the telephone, which is 1 minute (15 m/s * 1 minute = 15 meters). Then, we can calculate the time it took him to get back, which is 3 minutes (4 m/s * 3 minutes = 12 meters). The total distance is 15 meters + 12 meters = 27 meters.
