Lyla and Alexis went to the Sea World. They want to go down all the water slides. On one of the slide, the worker told the girls if they want to go fast, to put their hands up and don't touch the sides. How would this help the girls go fast?
There would less friction; touching and hanging on to the sides could slow them down.
