Answer: 0.2
Explanation:
To calculate the distance that Joanie run during her lunch break is necessary to multiply the total distance around the outside of Cedar Park (0,8) by the 1/4 of the total distance that she ran (0,25).
So, the expression is:
0,25 . 0.8 = 0,2
Joanie run 0,2 miles during her lunch break.
