"One of the problems given to lady candidates for civil-service appointments in a late examination was as follows: "A starts to walk from one town to another at the average rate of three miles an hour; forty minutes later a bicyclist (B) starts on the same journey at the rate of twelve miles an hour. On reaching the second town B rests half an hour, and, after riding forty minutes on his return journey, meets A still on his way. Find the distance between the two towns.""
