Justin can run 2 blocks in 1.5 minutes. If he is 8 blocks from home, in how many minutes can he run home?
assistant
How many blocks are in each set? ** There are 8/2 = <<8/2=4>>4 sets of two blocks that Justin can run.
How many minutes can he run home? ** Thus, he can run home for 4 x 1.5 = <<4*1.5=6>>6 minutes.
