Support your answer with Reason.

Answer 1

Dear Student
$$\begin{gathered} Initialreading=1262Km \\ Finalreading=1342Km \\ Displacement=1342-1262=80Km \\ Time=15min=\frac{15}{60}=0.25hr \\ Averagevelocity=\frac{Displacement}{time}=80/0.25=320kmh{r}^{-1} \\ 2)Thespeedometershowstheins\tan \tan eousvelocitysothevehiclewillshow \\ thereadingwhenitismoving. \\ REGARDS \end{gathered}$$
