Well the cyclist would catch up at 48 miles because......6, 12, 18, 24, 30, 36, 48, 54, 60 and 16, 32, 48, 64, 80. Now if you find the least common factor between the two that is your answer. which is48 in this case

If the runner moves at 6 miles per hour for 2 hours before the cyclist starts, the runner has a 12 mile lead at the beginning. If the cyclist is going at 16 miles per hour, he is overtaking the runner at 10 miles per hour, because 16-6=10. Then, the amount of time it takes the cyclist to go 2 miles in 10 miles per hour is the answer. this is 1/5 of an hour, or 12 minutes.
