Joel has already run 3 miles on his own, and he expects to run 2 miles during each track
practice. How many track practices would it take for Joel to run 49 miles?
Since Joel has already ran 3 miles, you can subtract it from 49. Now all he has left to run is 46 miles. Divide 46 by 2 and you get 23. That's how many practices it would take to get to 49 miles.
