C. 1.1 m/s east
Explanation
Step 1
Diagram
Step 2
Velocity is defined as a vector measurement of the rate and direction of motion.
we can find the manginutde of the velocity using the formula:
[tex]velocity=\text{ }\frac{distance}{time}[/tex]so
a)let
[tex]\begin{gathered} distance=\text{ 45 meteres} \\ time=42\text{ sec} \end{gathered}[/tex]b) now, replace in the formula
[tex]\begin{gathered} velocity=\text{ }\frac{distance}{time} \\ velocity=\frac{45\text{ m}}{42\text{ s}}=1.07\frac{m}{s}\approx1.1\frac{m}{s} \end{gathered}[/tex]so, the magnitude is 1.1
c) finally, The direction of a vector can be described as beingeast or west or north or south,therefore, as the person goes from west to east the answer is
C. 1.1 m/s east
