joseph needs to run 3 miles during his workout for the soccer team. he begins by running 1/2 half and he takes 3 breaks during practice to run 1/4 mile each time how much more will he need to run at the end of practice to finish his 3 miles

At the end of practice, Joseph will need to run another 1.75 miles or 1 3/4 miles.

To determine this we need to subtract the amounts he already has run during practice from the goal of 3 miles.

3 miles - 1/2 miles - 1/4 miles - 1/4 miles - 1/4 miles = 1.75 miles
