Which statement describes the difference between speed and velocity
a. velocity is speed with a direction. b.velocity is speed divided by time. c.velocity is speed multiplied by time. d.velocity is measured in meters per second while speed is measured in meters.

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
