## Homework Statement

Billy has 1 penny, 1 nickel, 1 dime and 1 quarter. How many different ways can he put his coins in the following board by placing one coin in each cell?

Juan walks to school everyday. His walking speed is 1/15 mile per minute, and it takes him 30 minutes to get to school. His sister Gabriela bikes to school every day. Her biking speed is 1/10 mile per minute. How many minutes does it take Gabriela to get to school?

## The Attempt at a Solution

Not sure how to do the first one. The second one I got the answer by multiplying Juan's speed x time to get the distance he traveled. Then with that distance, I divided it by Gabriela's speed to get how long it takes her. But the problem says nothing about the distances being the same, I just don't know
