A student is experimenting with lightning rods and places one into the ground. She finds that the approximate length of rod above ground is 5/7 of a yard and the approximate length below ground is 1/3 of a yard. How many times farther above the ground is the lightning rod than below the ground?

1 answer

First find the length of the rod above ground: 5/7 yard = <<5/7=.7142857142857143>>.7142857142857143 yard
Then find the length of the rod below ground: 1/3 yard = <<1/3=.3333333333333333>>.3333333333333333 yard
Then divide the length above ground by the length below ground to find the ratio of the two lengths: .7142857142857143 yard / .3333333333333333 yard = 2.142857142857143. Answer: \boxed{2}.
