Brenna ran a total of 8 miles over the course of 4 track practices. How many track practices would it take for Brenna to run 16 miles? Assume the relationship is directly proportional.

8 in total

Step-by-step explanation:

8 miles in 4 track practices, that's 2 miles every practice, you just multiply or add. She needs 4 more track practices because 8 x 2 is 16, which is how many miles she runs every practice. If you put 4 more practices it would be 16 miles and 8 practices in total. Sorry if this didn't make sense or confused you, I'm not the best at explaining but you're answer for the total amount of practices is 8.
