Adding their rates of travel, 40%2B80=120 km/hour, 120%2Ah=75 would be an equation showing the variable for h hours when A and B would meet. h=5%2F8 hours. BUT we want 1%2F60 hour LESS than that.

The amount of travel time we want to use is 5%2F8-1%2F60,
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 73%2F120 of an hour.
Using rate*time=distance, we can find how far in total they have traveled, meaning the sum of their traveled distances:
120%2A%2873%2F120%29=73 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 75-73=2 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.
