What is the vertical distance to the bottom of the run? Been trying to figure this out for hours. I still don't understand please help

Shari uses the data in the table to predict how her weight on venus would compare with her weight on earth. which is the best prediction shari could make? her weight is greater on venus because venus has less mass. her weight is lower on venus because the acceleration due to gravity is lower. her weight is lower on earth because it is farther from the sun. her weight is greater on venus because venus has a smaller diameter.
