The distance d a train travels varies directly with the amount of time t that has elapsed since departure. If the train travels 475 miles in 9.5 hours, how many miles did the train travel after 4 hours?

O 232.5
300
To find the constant of variation, divide the distance traveled by the time elapsed:
475 miles / 9.5 hours = 50 miles/hour
Now use this constant of variation to find how many miles the train traveled after 4 hours:
50 miles/hour * 4 hours = 200 miles
Therefore, the train traveled 200 miles after 4 hours.
