Trent walked 4 blocks from his house to the bus stop. He rode the bus 7 blocks to the library. Later, he came home the same way. How many blocks did Trent travel in all? Give me reasons, before answering the question

On the way to the library, Trent went 4 blocks + 7 blocks = 11 blocks. Trent came home the same way so he went 11 blocks + 11 blocks = 22 blocks. So the final answer is 22.
