This average velocity results, because she hikes for 6.16 km with an average velocity of 2.09 m/s due west, turns around, and hikes with an average velocity of 0.324 m/s due east. How far east did she walk (in kilometers)?

饾摜 = (d鈧?+ d鈧? / (t鈧?+ t鈧?
饾摜 = (d鈧?+ d鈧? / (t鈧?+ t鈧?
饾摜 = (d鈧?+ d鈧? / (d鈧?v鈧?+ d鈧?v鈧?
饾摜 = v鈧乿鈧?d鈧?+ d鈧? / (v鈧乨鈧?+ v鈧俤鈧?

饾摜 = v鈧乿鈧?d鈧?+ d鈧? / (v鈧乨鈧?+ v鈧俤鈧?
1.49 = 2.09*0.324(6.16 x 10鲁 + d鈧? / (2.09d鈧?+ 0.324*6.16 x 10鲁)
