A train leaves boston and travels toward its destination at a speed of 60 mph. One hour later, an express train leaves Boston an
Margarita [4]

Taking into account the supplied speeds, Boston is from the destination to:

  • 240 miles

<h3>Calculation of the distance between Boston and Place of Destination</h3>

To identify the distance between Boston and the destination of the trains, it must be remembered that the <u>speed</u> mentioned for each one is a reference to the distance traveled per hour, therefore, after each hour, each train will travel :

  • Regular train: 60 miles
  • Express train: 80 miles

According to the information given, when the express train leaves, the regular train has a 60-mile lead, which is getting shorter hour by hour because the express train travels 20 miles per hour more than the normal train.

Therefore, in <u>three hours</u>, the express train would catch up with the regular train, calculating the distance thanks to the speed formula:

  • Speed =\frac{Distance}{Time}

And clearing the distance:

  • Distance=Speed*Time
  • Distance=80\frac{miles}{hour}*3hours
  • Distance=240miles

Therefore, the destination would be <u>240 miles</u> from Boston, which would take four hours by regular train and three hours by express train.
