Question 9
Alex and Boris live in the same village. One day, both of them left their village at the same time to travel to the city, where it is known that they have different constant speeds. At a certain moment in the journey, we know that if Alex had gone three times as far as he had so far, he would have half as far to go, and if Boris had gone half as far as he had so far, he would have three times as far to go. How many times is Boris faster than Alex?
