Question

if a car covers a distance 100 km in h and same distance is covered by it in 5 h.find the average velocity

Answer 1

Total distance = 200 km
Total time = 6 h

avg velocity = 33.34 km / h

Answer 2

As velocity is a vector quantity,
There are two cases,
1st case, when the car travels from initial point to final point and again from the final point back to initial point
Then ,
Displacement =0
Avg velocity=displacement/time=0
2nd case, when the car doesn't return back to the initial point
Then displacement =200
Avg velocity=200/6=33.33
