Sam Loyd's Jack and Jill Puzzle
The distance to the top of the hill was 440 yards, which is just a quarter of a mile.
Jack got to the top first and was 20 yards on the return trip when he met Jill whom he beat home by half a minute.
The record of the race is complicated by the runners being able to run down hill one-half again faster than they ran up, so you are asked to figure out Jack's time for the half mile run.
