When calculating speed what goes into the calculator first A. Time
B. Distance
C. Speed

B. Distance

Explanation:

When calculating speed, the value of the given distance is first entered on the calculator because it is in the numerator.

Speed is the rate of change of distance with time;

       Speed  =  

The value of the distance is inputted first before that of the time is entered.

This way the division sign evaluates for the speed.

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
