<PRE><B>Question 196841</B>
Force on running shoes. The ratio of the force on the shoe soles to the weight of a runner is 3 to 1. What force does a 130-pound jogger exert on the soles of her shoes?
---------------
Proportion:
Force/weight = 3/1
Your Problem
Force/130 = 3/1
Force = 130(3/1) = 390 lbs.
