anonymous · Answer

In one hour, one car travels a distance of 65 miles, the other car travels a distance of 50 miles. 

Thus, in one hour, the total distance between the 2 cars is 65+50 = 115 miles

To find the time taken for the cars to be 575 miles apart. Take 575 and divide it by 115. 

575/115 = 5 hours.
