The distance d a train travels varies directly with the amount of time t that has elapsed sence departure if the train travels 475miles in 9.5 hours how many hours did the train travel in 4 hours

Respuesta :

distance = 475 time = 9.5 hrs since distance and time varies directly therefore in 9.5 hrs train travels 475 miles => In 1 hr train travels 475 / 9.5 miles = 50 miles and in 4 hrs train travells 50*4 i.e 200 miles
Speed of the Train = 475/9.5 = 50 mph

Now, In 4 hours, 

d = 50 * 4 = 200 miles

In short, Train traveled 200 miles in 4 hours

Hope this helps!
