So if we subtract 14 from 35 we get 21. and if you convert 112 minutes into hours we get 1 hour and 52 minutes, so if we were to convert it into mph we would get 7 because its half of 14 and it took her 2 hours to reach that amount.
So now we just multiply until we reach 35.
7*5=35
So your answer would be around 5 hours.
