 * Out and Home
 * Mr Wilkinson walks from his country house into the neighbouring town at the rate of five miles per hour,
 * and, as he is a little tired, he makes the return journey at the rate of three miles per hour.
 * As the double journey takes him exactly seven hours, can you tell me the distance from his house to the town?
