Randy rode his bike 1.23 miles to school from his house. After school, he rode 0.9 miles farther to the library. Randy biked home along the same route, stopping at a park 1.05 miles from the library. How many miles is the park from Randy's house?
3.18 because you have to take your original number 1.23 then add 0.9 for the library which is 2.13 then you have to add the distance to the park which is 1.05 and if you add all that up you get 3.18
