The correct option.

Answer to Problem 1FC
The correct option is, “(b) Displacement is a vector, while distance is not a vector”.
Explanation of Solution
Formula used:
Write the expression for average speed as follows:
Explanation:
Re-arrange Equation (1) as follows:
The displacement is difference between the final and the initial position of an object.
Find the displacement as per the equation given below:
Distance conveys information only about the magnitude. Displacement is a vector that conveys the magnitude and direction. Therefore, displacement is a vector, while the distance is not a vector. Therefore, option (b) is correct and options (a) and (c) are incorrect.
Conclusion:
Hence, the correct option is, “(b) Displacement is a vector, while distance is not a vector”.
