To determine the distance from the School to Track Field, we will sum the distances from the School to the Library with the distance of the library untill the Track Field:
we need to put both fractions with the same denominator, as follows:
From the solution developed above, we are able to determine that the distance from the school to Track Field is equal to 7/20 kilometers, and it was determined by summing the distances from School to Library, with the distance of the library until the Track Field.
