Ainsley lives in a town 360 miles directly north of Orlando, and one Saturday, she takes the train from her town to the city. he train travels at a constant speed, and after 2.5 hours, she sees a sign that states "Orlando: 210 miles". What is an equation that represents (x), the distance Ainsley is from Orlando after x hours.

By definition we have to:

d = v * t

where,

d: distance

v: speed

t: time

We have then that the speed is:

(360-210) = v * 2.5

Clearing we have:

v = (360-210) / 2.5

v = 60 mph

We now write the generic equation of distance:

d (x) = 60x

Where,

x: time

Answer:

an equation that represents (x), the distance Ainsley is from Orlando after x hours is:

d (x) = 60x
