Marathon Distances and Scientific Notation

The video tutorial explains how to calculate the total distance run by 50,000 finishers of the 2015 New York City Marathon, each running 26.2 miles. The total distance is converted into scientific notation and compared to the Earth's circumference to determine how many times the runners could circle the Earth. The final result shows that the runners would have run around the Earth 52 times.

How many finishers were there in the 2015 New York City Marathon?

• 40,000
