If a train leaves the station at 7:00 AM and travels at 56 mph, at what time would it arrive at the next town that is 450 miles
ELEN [110]

Answer:

Step-by-step explanation:

This is a simple motion problem.  Believe me, they get much harder!  The distance formula is

d = rt

We want to know, basically, how long it will take this train traveling 56 mph to go 450 miles.  We have the r, rate, and the d, distance:

450 = 56t so

t = 8.0

That means it will take 8 hours for the train to travel that far.  If it leaves at 7 am, 8 hours after that will put it in the next town at approximately 3pm.
