Question

anonymous · Answer

total time that took son to reach 130miles = 130/12=10.833
total time that took father to reach 130miles = 10.833 + 0.75 = 11.5833 hours
(here 0.75hours=45mins)
rate at which father drove = 130/11.5833 = 11.223 miles per hours

ok, but i have an answer sheet that has a write answer and a wrong answer and u have to choose the right one, the two choices are 40 and 2.4

well to my knowledge, I think I got the right answer. If you really want to stick to one of your answers, then think like this.
father's rate should be lower than son's because it is obvious here. So 40 cannot be the answer.
