Jack and Jill went on a hiking trip up a hill. The trail was 10 miles long. On their way back they were coming down hill so their speed was 25% faster than their speed on the way up. The entire trip took 6 hours including a one and a half hour long lunch break at the top of the hill. What was their speed on their way down the hill?
