1.2 A non-stop freight train leaves Edinburgh for London at 6:00 and travels at a steady 75mph (time taken to accelerate is negligible) for the 332 miles. A passenger train leaves at 7:00 and travels at 126 mph (again time taken to accelerate is minimal) however it stops every SOmins for a period of 10 minutes before continuing In a table show the distance that each train has travelled at each hour into the journeys Plot...
