Answer:To find out how far he walks, we need to multiply the number of blocks by the length of each block.
Given that each block is 2/3 mile long, and he walks 4 1/2 blocks, we can calculate the distance as follows:
1. Convert the mixed number 4 1/2 to an improper fraction: 4 1/2 = 9/2.
2. Multiply the number of blocks by the length of each block: (9/2) * (2/3) = 18/6 = 3 miles.
Therefore, he walks a total distance of 3 miles.
