Given :
Distance travelled from Mumbai to Pune = 150km
Distance travelled from Pune to Mumbai = 180km
t₁ = 150 min
t₂ = 210 min
To find :
Average velocity for the entire journey
Solution :
- Average velocity = Total displacement / Time taken
- In this case the journry stars from Mumbai and again the journey ends in mumbai which means the displacement of particle is zero though the paths followed during the journey are different.
- Average velocity = 0/t₁+t₂
- Average velocity = 0
The average velocity for the entire journey is 0m/s
