This question isn't in the textbook - it's the Problem of the Week. This question is from textbook Saxon Math Course 3
You can put this solution on YOUR website! On a stretch of road 75 miles long, two trucks approach each other. Truck A is driving 55 mph and Truck B is going 80 mph. What is the distance between the two trucks one minute before their head-on collision?
----------------------------------------------
The closing speed is 55+80 = 135 mph
In one minute the trucks will cover 135/60 = 2.25 miles
--------------------------------
That is how far they are away from one-another one-minute before
they would have a head-on collision.
