Mario walked his dog 5 miles. He walked 3 1/5 miles from home to the post office, and then walked to the library before going home. Mario lives 1 1/2 miles to the library. How far is it from the post office to the library?

• 5th grade problem solving -

5 = 3.2 + (library to PO distance)+ 1.5
= 4.7 + (library to PO distance)

library to PO distance = 0.3 miles
