Final answer:
The first relay exchange occurs before 0.2 miles.
Step-by-step explanation:
The relay race is 2 miles long and there are 11 students participating. In order to split the distance equally, each student will run approximately 2/11 miles. To determine if the first relay exchange occurs before or after 0.2 miles, we need to compare 2/11 miles to 0.2 miles. We can convert 2/11 to a decimal by dividing 2 by 11, which gives us approximately 0.1818 miles. Since 0.1818 miles is less than 0.2 miles, the first relay exchange occurs before 0.2 miles.
