Xavier runs three times as many miles as Katie, who runs 4 times as many miles as Cole. If Xavier runs 84 miles, how many miles does Cole run?
Katie runs one-third of Xavier's distance, which is 84/3 miles = <<84/3=28>>28 miles.
Cole runs a quarter of Katie's distance, which translates to 28/4 = <<28/4=7>>7 miles.
