Javier's grandmother lives 120 miles away it takes 1 hour to travel 40 miles by train it takes 1 hour to travel 6 miles by car if Javier leaves at 7 A.M. Is it reasonable to say he will arrive at his grandmother's by 9 A.M. If he takes the train? What if he drives by car

Respuesta :

it would not be reasonable to leave at 7 and arrive at 9 because that would be a total of 2 hours driving and 2 hours on a train equals to 80 miles. and to drive by car it would take a total of 20 hours.
