Tim is running a distance of 30 city blocks. Each block is the same length. It took him 6 minutes to run 10 blocks. At the same rate, how
many minutes will it take Tim to run the entire 30 blocks?
You can answer this because you know that 10 x 3 is 30, so if if the number of blocks tripled then the amount of time should triple as well because he's running at the same rate.
