Question

A car travels a distance of 15 km towards east,20 km towards the south and then 45 km towards east. Find the total distance and displacement travelled by car

Answer 1

Dear Student,

Distance travelled=15+20+45=80 km
Displacement is given as shortest distance joining initial and final position.

$$\begin{gathered} i.ethediagonalk=joiningstartingandendposition. \\ co-ordinatesofendposition=(60km,20km) \\ co-ordinateofstart\left(say\right)(0,0) \\ shortestdis\tan ce=\sqrt{{60}^2+{20}^2}\Rightarrow 63.25km \end{gathered}$$

Regards.
