Peter is walking from the library to school at a rate of 40 meters per minute. At the same time, Paul is walking from school to the library. After they meet each other, Peter still needs 6 minutes to get to school, while Paul is 200 meters away from the library. What is the distance (in meters) between the school and the library
d = 40m/min*6min + 200m = 440 m.
