a train has an average speed of 18 miles per hour how long will it take to travel 270 miles?
If the train travels 18 mph you just have to divide 270 by 18 and that would be your answer.
So 270/18 = 15 which means it would take the train 15 hours to travel 270 miles.
Hey there,
Make a proportion: 18 miles/1 hour=270 miles/x hours.
Now, we cross multiply, 18x=270.
18x/18x=270/18.
270/18=15.
Answer:x=15 hours
