Mr. Garcia's science class did an experiment to see who could walk the greatest distance in a certain amount of time. Mr. Garcia told his students he would measure how far they walked during the school day, from 9:00 AM until 3:00 PM. That is, all the students walked for 6 hours. The next day, the class graphed the data. Here is a comparison of the boys and girls: how far they walked in 6 hours. Which group walked the fastest? A) 4 mile group B) 5 mile group C) 6 mile group D) 7 mile group
