<human>:  Jack and Jill race up the hill to see who gets there fastest. Jack ran up the first half of the hill in 19 seconds. He finished running up the hill 7 seconds before Jill did. If Jill finished the race in 32 seconds, how long did it take Jack to run up the second half of the hill?
<bot>: How long did Jack run up the hill? ** Since Jack was faster than Jill, his total running time must have been 32 - 7 = <<32-7=25>>25 seconds.
How long did Jack run up the second half of the hill? ** Subtracting the the time he spent running up the first half of the hill shows that it took 25 - 19 = <<25-19=6>>6 seconds to run up the second half of the hill.
