John skateboarded for 10 miles and then walked another 4 miles to the park. He then skated all the way back home. How many miles has John skateboarded in total? Give me reasons, before answering the question
John traveled 10 + 4 = 14 miles to the park. His round trip would take 14 x 2 = 28 miles. If you subtract the 4 miles he walked then John traveled 28 - 4 = 24 miles. So the final answer is 24.
