Answer:
To find the total distance that Shaylyn drove, we need to add up the distance she drove to the gym, the distance she drove back home, and the distance she drove back to the gym to retrieve her gym bag.
The distance Shaylyn drove to the gym is given as 5 1/4 miles.
The distance she drove back home is also 5 1/4 miles since she retraced her route.
The distance she drove back to the gym to retrieve her gym bag is given as 2 1/2 miles.
So, the total distance that Shaylyn drove is:
5 1/4 + 5 1/4 + 2 1/2 = 13 miles
Therefore, Shaylyn drove a total of 13 miles.
