Answer:
You start your trip in St. Paul, Minnesota, which is about 87.6 miles from the source of the Mississippi River. After traveling down the river for over 500 miles, you reach the large city of St. Louis, Missouri. You continue on to
Cairo, Illinois. A few miles past this town, you arrive at the place where another large river called the Ohio River flows into the Mississippi. Continuing down the Mississippi for over 600 more miles, you finally reach the mouth of the river at the city of New Orleans Louisiana. Here, the Mississippi flows into a large body of water called the Gulf of Mexico.
