A man started at the home and travels to a vegetable market, which is a distance of 2.5km from the home .
The total time taken by the person to return back to home is 2hrs .
To find -
What is the average speed and velocity of the man ?
Solution -
Here , A man started at the home and travels to a vegetable market, which is a distance of 2.5km from the home .
Let us calculate the distance and displacement of the man .
Now , as the person starts from home , goes to the vegetable market and returns back home ,
Displacement -
=> ( + 2.5 km ) + ( - 2.5 km )
=> 0 km
Distance -
=> 2.5 km + 2.5 km
=> 5 km .
Average Velocity -
=> [ Displacement ] / [ Time ]
=> [ 0 km ] / [ 2 hr ]
=> 0 kmph
Average Speed -
=> [ Distance ] / [ Time ]
=> [ 5 km ] / [ 2 hr ]
=> 2.5 kmph.
This is the required answer .
