Answer: 13 hours

Step-by-step explanation:

1755 / 2 = 877.5

877.5 / 70mph = 13.5 hours

877.5 / 65mph = 12.5 hours

Since we are trying to find the distance between the two trucks, I found the middle of these two answers since they are driving at different speeds. This gave me 13 hours, so I checked it using the equation below.

1755 = 70x +65x

1755 = 70(13) + 65(13)

1755 = 910 + 845

1755 = 1755

I also got it right on the chapter 5 test in the Algebra 2 Teaching Textbook.

Hope this helps :)
