*if you traveled one mile at a speed of 100 miles per hour and another mile at a speed of 1 mile per hour, your average speed would not be (100 mph + 1 mph)/2 or 50.5 mph. what would be your average speed? (hint: what is the total distance and total time? )

The answer is 1.818 (if rounded to the nearest thousandth). 

This is because when you travel the first mile, it takes you only .1hrs. When you travel the second mile, it takes a full hour. Thus you have travelled 2 miles in 1.1hrs. When you divide the 2 by 1.1, you get the answer above.
