Enigma Number 1534

摘要

Harey and Tortus decided to race from Harey's house to school, a distance of a whole number of metres. They each ran at their own steady speed and when Harey reached school, Tortus was over half way there, but still had a two-figure number of metres to go.rnThe next day they repeated the race, but this time Harey decided torngive Tortus a head start equal to the winning margin of the previous day. So Harey walked that number of metres away from his house in the opposite direction to school before the race started. Once again, Harey got to school first, ahead by a two-figure number of metres. The second winning margin had the same pair of digits as the first, but in reverse order.
