A jogger goes for a 3-mile run. She finished in a time of 23 minutes and 14 seconds. The first mile she ran in 8 minutes and 30 seconds. She ran the second mile in 7 minutes and 52 seconds.

How fast was the third mile?

Choose the equation the best represents the time of the third mile.


$8m \space 23s - 7m \space 52s = 23m \space 14s$


$23m \space 14s - 8m \space 23s - 7m \space 52s = x$


$8m \space 23s + x - 7m \space 52s = 23m \space 14s$


$x - 23m \space 52s = 7m \space 52s$
