<human>:  Milo can roll downhill on his skateboard at twice the speed that he can run. And Milo's best friend, Cory, can drive his wheelchair at twice the speed that Milo can roll downhill on his skateboard. If Cory always drives his wheelchair at 12 miles per hour, how many miles can Milo run in two hours?
<bot>: How fast does Milo roll downhill on his skateboard? ** Since Cory drives his wheelchair at 12 miles per hour, then Milo rolls downhill on his skateboard at 12/2 = <<12/2=6>>6 miles per hour.
How fast does Milo run? ** Therefore, Milo runs at 6/2 = <<6/2=3>>3 miles per hour.
How many miles will Milo travel in 2 hours? ** If Milo runs for 2 hours at 3 miles per hour, then Milo will travel 2 * 3 = <<2*3=6>>6 miles.
