Answer 2

Answer: Her average speed would be 8.89 miles per hour.

Step-by-step explanation:

Since we have given that

Time taken  to run from mile marker 1 to mile marker 2 = 6 minutes

Time taken to run from mile marker 2 to mile marker 4 = 21 minutes

So, Number of miles from 1 to 4 = 4 miles

total time taken = 6+21 = 27 minutes

So, Average speed would be

$\dfrac{4}{27}\times 60\\\\=\dfrac{240}{27}\\\\=8.89\ mph$

Hence, her average speed would be 8.89 miles per hour.
