Taro left the house for the station and Jiro left the station for the house simultaneously.
Both of 2 people walked by a fixed speed respectively.
The distance between two persons was 632 m 5 minutes after leaving and it was 112 m 13 minutes after leaving.
When 2 people didn't pass each other in 8 minutes during 13 minutes later from 5 minutes later.
Because the distance 2 people moved in 8 minutes was 632 - 112 = 520m, the total speed per minute of 2 people is 520 / (13 - 5) = 65m/min.
Therefore the distance between the house and the station is 632 + 65 × 5 = 957 m.
Case 2 :
When 2 people passed each other in 8 minutes during 13 minutes later from 5 minutes later.
Because the distance 2 people moved in 8 minutes was 632 + 112 = 744m, the total speed per minute of 2 people is 744 / (13 - 5) = 93m/min.
Therefore the distance between the house and the station is 632 + 93 × 5 = 1097 m.
