<human>:  Mary, Edna, and Lucy are athletes who train every Saturday. Mary ran 3/8 of a 24-kilometer field on one Saturday. Edna ran 2/3 of the distance of Edna, and Lucy ran 5/6 of the distance of Edna. How many more kilometers should Lucy run to cover the same distance as Mary?
<bot>: How many kilometers did Mary run? ** Mary ran 3/8 x 24 = <<3/8*24=9>>9 kilometers.
How many kilometers did Edna run? ** Edna ran 2/3 x 9 = <<2/3*9=6>>6 kilometers.
How many kilometers did Lucy run? ** Lucy ran 5/6 x 6 = <<5/6*6=5>>5 kilometers.
How many more kilometers should Lucy run to cover the same distance as Mary? ** Lucy should run 9 - 5 = <<9-5=4>>4 kilometers more.
