Velocity(speed with direction)

Q. A car travels from Bangalore to Mumbai and returns in $20hours$. What is the average velocity and average speed of the car if odometer reading of the car, when it started was $2200km$ and when finished was $3800km$?

1. $\text{Average velocity = 0 kmph}$
   $\text{Average speed = 0 kmph}$
2. $\text{Average velocity = 0 kmph}$
   $\text{Average speed = 80 kmph}$
3. $\text{Average velocity = 80 kmph}$
   $\text{Average speed = 80 kmph}$
4. $\text{Average velocity = 80 kmph}$
   $\text{Average speed = 0 kmph}$

Q. A body goes from C to D with a velocity of $20m{s}^{-1}$ and comes back from D to C with a velocity of $30m{s}^{-1}$. The average velocity of the body during the whole journey is:

2. $26m{s}^{-1}$

3. $25m{s}^{-1}$

4. 0

2. 31.4 cm, 31.4 cm/min, 20 cm, 20 cm/min
3. 314 cm, 314 cm/min, 0.1 cm, 0.1 cm/min
4. 0.314 cm, 0.314 cm/min, 1 cm, 1 cm/min
