Respuesta :
It depends on where each train its heading is both trains destination is 600 miles apart from each other then, Train A is going 70mph so divide 600 by 70 to get 8.57 round it up to get 8.58 then multiply by 70 to get 600.4 round down to get 600. Train B is going 80mph so divide 600 by 80 to get 7.5 then multiply by 80 to get 600. The trains should be 600 mi apart by 1 hour and 14 minutes.
