Let D be that "one way" distance, in miles. The time spent on the way to the library is hours. The time spent on the way back is hours. The equation for the total time spent is + = 2 hours. // This equation is the DIRECT translation of the condition (!) To solve it, multiply both sides by 12. You will get 2D + D = 2*12 ====> 3D = 24 ====> D = = 8. Answer. One way distance is 8 miles. Check. Time "to there"" = = hours. Time back = = hours + = = 2 hours. ! Correct !

Solved.
