Question

In reaching her destination, a backpacker walks with an average velocity of 1.01 m/s, due west. This average velocity results, because
she hikes for 5.44 km with an average velocity of 2.59 m/s due west, turns around, and hikes with an average velocity of 0.397 m/s due
east. How far east did she walk (in kilometers)?

Expert Solution

Step 1: Average velocity

Write the expression for the average velocity and elaborate the expression.

$table row cell v subscript a v g end subscript equals fraction numerator capital delta d over denominator capital delta t end fraction end cell row cell v subscript a v g end subscript equals fraction numerator d subscript w e s t end subscript minus d subscript e a s t end subscript over denominator t subscript w e s t end subscript plus t subscript e a s t end subscript end fraction end cell row cell v subscript a v g end subscript equals fraction numerator d subscript w e s t end subscript minus d subscript e a s t end subscript over denominator d subscript w e s t end subscript over v subscript w e s t end subscript plus d subscript e a s t end subscript over v subscript e a s t end subscript end fraction end cell end table$
