Video Summary

In this discussion, a train company is planning to install a double track to prevent collisions between two trains traveling concurrently from points X and Y. The train from Y is three times faster than the train from X, taking 60 minutes compared to 180 minutes for the train from X. The critical point where the trains meet is when train Y has traveled 45 units and train X has traveled 15 units, given the total distance is 60 units. Therefore, placing the double track around 15 and 45 units on the track ensures safety, making option B the recommended location.
