Which of the following pairs contains one vector and one scalar quantity?

 

A vector $\mathbf{P}$ of magnitude $3.0 \mathrm{N}$  acts towards the right and a vector $\mathbf{Q}$ of magnitude$4.0 \mathrm{N}$ acts upwards. What is the magnitude and direction of the vector $(P-Q)$?

A car travels one complete lap around a circular track at a constant speed of $120 \mathrm{kmph}$. If one lap takes $2.0 \min .$, show that the length of the track is $4.0 \mathrm{km}.$

A car travels one complete lap around a circular track at a constant speed of $120 \mathrm{kmph}$. If one lap takes $2.0 \min .$

Explain why values for the average speed and average velocity are different
