Question

A car moving on a ground covers distance 1 km towards east in 120 seconds and take turns toward North

and covered 1 km in 100 seconds. Find the average velocity and average speed.​

Answer 1

Answer:

speed (1)

= 1km in 120 seconds

= 1000/120 m/s

= 8.33 m/s

speed (2)

= 1 km in 100 seconds

= 1000/100 m/s

10 m/s

Average Speed

= (speed1 + speed2)/2

= (8.33 + 10)/2

= (18.33)/2

= 9.16 m/s
