Moses and Tiffany want to see who is faster. But instead of a race, they just start running down the block. Tiffany runs 6 blocks in 3 minutes. Moses runs 12 blocks in 8 minutes. What is the speed (defined as blocks per minute) of the runner with the higher average speed?
Tiffany runs 2 blocks per minute because 6 / 3 = <<6/3=2>>2
Moses runs 1.5 blocks per minute because 12 / 8 = <<12/8=1.5>>1.5
The runner with the highest average speed is Tiffany because 2 > 1.5
