A passenger train travels between two cities at a constant speed. After 6 hours,
it has traveled 450 miles. After 9 hours, it
has traveled 675 miles. Which equation
shows the relationship between the
distance d in miles and the time t in hours?

The train travels 75 mph.

Step-by-step explanation:

Hope this helps!

(75, 1)

Step-by-step explanation:

One way we can figure out how fast the train goes, is bylooking at what we have. We know that the train travels 450 miles in 6 hours. When we divide, we get 75. So, we know that the train is going at 75 miles per hour. We can check our work by looking at the second relationship on there. When 675 is divided by 9, we get 75. So for every hour, the train travels 75 miles.

I hope that this helps you out :)
