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? Let's be accurate as possible.
Katie runs one - third of Xavier's distance, which is 84 / 3 miles = 28 miles. Cole runs a quarter of Katie's distance, which translates to 28 / 4 = 7 miles.
The answer: 7.
