A body travelling along a straight line ...

A body travelling along a straight line path travels first half of the distance with a velocity `7 ms^-1` . During the travel time of the second half of the distance, first half time is travelled with a velocity `14 ms^-1` and the second half time is travelled with a velocity `21 ms^-1`. Then the average velocity of the body during the journey is

`14 m s^-1`

`10 ms^-1`

`9 ms^-1`

`12 ms^-1`
