Anthony decided to run one mile every 5 days. John decided to run two miles every 6 days. If they both start on Saturday, April 14, when will they both run on the same day again?
April 14 + 5 days = April 19 (Anthony)
April 14 + 6 days = April 20 (John)
6 days x 5 days = 30 days
April 14 + 30 days = May 14, Monday
