If it takes 2 1/2 hours to drive 140 miles to his grandmother, what is the average speed per hour he traveled

First you need to set what you have as a ratio
you are given 140 and 2.5 hours
thus allowing you to simplify this ratio to 56
140/ 2.5 = 56 mph

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
