Adding their rates of travel, km/hour, would be an equation showing the variable for h hours when A and B would meet. hours. BUT we want hour LESS than that.
The amount of travel time we want to use is ,
LCD = 2*2*2*3*5,
hours
Our two trucks are heading toward each other at 120 km/hour, and the time of 1 minutes less than the needed time for them to meet is of an hour.
Using rate*time=distance, we can find how far in total they have traveled, meaning the sum of their traveled distances:
km. they have moved on this road path.
The difference between this road path length and how much they traveled 1 minute before meeting is then kilometers.
-----------------------------------------------
TWO Kilometers apart, 1 minute before meeting.

-------------
120 km/hr = 2 km/min
1 minute prior, they're 2 km apart.

The 75 km is not relevant.
