Draw a picture and label how far the distance is, then use your pencil to trace the path out, remembering that you are following her same mistakes. then add up the total distance.

let x = home to training
2x/3 = home to work
x/3 = 2.5 km work to training

so 2x/3 = 2 (2.5) = 5

today's travel:
home to work 5 + work to home 5 + home to training (5 + 2.5) and back (5 + 2.5) = 25 km
is it right??
