Sam's Earth Science class is about to walk the planets. What does that mean? Well, his teacher has tied a large helium balloon outside and students will pace off the distance to each planet, using this scale as a guide. Sam's teacher has told the class to use the idea of a "pace" as a unit of measure for the activity. A pace is two steps-one with each foot. One pace is about 1 meter. The students predicted how many paces it would take to reach each planet. It takes 6 paces to reach Mercury. How many paces from the Sun is Venus?
