Can anyone help with this problem? A 65 kg girl stands in the middle of her 20 kg canoe. The canoe is 3m long, and the end that is closet to land is 2.5m from the shore. The girl now walks toward the shore until she comes to the end of the canoe. What is the distance from the girl to the shore ?? I know its the formula x= m1x1+m2x2/ m1+m2 does anyone know how to solve it from there ?
