The distance between Athos and Aramis, galloping down the same road, is 20 leagues. In one hour, Athos covers 4 leagues,
while Aramis covers 5 leagues.
What distance will be between them after one hour?
Notice, nothing is said about whether the musketeers are galloping in one or different directions.
Solution
The musketeers could be riding:
a) in different directions, towards each other;
b) in different directions, moving away from each other;
c) in the same direction - Athos following Aramis;
d) in the same direction - Aramis following Athos.
Accordingly, the problem allows for four different answers. For example, in case a) the distance will decrease by 9 leagues in one hour and will be 11 leagues. Similarly, the other answers can be found.
Answer
11, 29, 21 or 19 leagues.
