Five friends each do the same amount of work lifting crates up onto shelves. The time it took each person are shown below in the table
Meg 2.5 Andrew 1.7 Ryan 3.2 Amy 1.5 Tom 2.2
Place the friends in order of increasing power

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
