Zac and Lynn are each traveling on a trip So far , Zac has traveled 123.75 miles in 2.25 hours . Lynn leaves half an hour after Zac . So far , she has traveled 105 miles in 1.75 hours . Assume Zac and Lynn travel at constant rates . Letr represent the number of hours that have elapsed since Zac started traveling . Let y represent the number of miles traveled . On a piece of paper , system of linear equations that represents the distance each of them has traveled since Zac left on his trip . Assume Zac and Lynn continue to travel same constant rates and make no stops . Part A Determine the solution of the system of linear equations . The solution is
