To solve this problem, we can set up a proportion using the given information.
We know that the distance d varies directly with the time t, so we can write the proportion as:
d / t = k
where k is the constant of variation.
We are given that the train traveled 475 miles in 9.5 hours, so we can plug these values into the proportion:
475 / 9.5 = k
Simplifying the left side of the equation, we get:
50 = k
Now we can use this value of k in the proportion to find the distance the train traveled after 4 hours:
d / 4 = 50
Solving for d, we have:
d = 4 * 50
d = 200
Therefore, the train traveled 200 miles after 4 hours. Answer: 200.
Question
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?
