Riddle
Question 3. See figure 2. Train A leaves station X at 8:45 travelling westward. Train B leaves station Y at 9:20 travelling eastward on the same track. Given that the standard speed on the line is 60 mph, at what time will they collide? Take into account the following factors: the driver of train A had three cups of coffee this morning and enjoys the hillside views; the driver of train B fell in love last night; the signal keeper at point Z got new binoculars for his birthday.
