Explanation:

which question would we answer

Answer 2

Answer:

1.speed- Speed is the rate of change in distance in a interval of time.speed=d/t.its a scalr quantity.

SI unit=m/s . it's depends upon only magnitude

velocity- it's us the rate of chnge in displacement in a interval of time.velocity =d/t.its a vector quantity.its depending upon both magnitude & Directions. SI unit =m/s .

2.average speed=total distance/total time taken

total distance=25860-25530=330

avg.speed=330/6=55km/hr

3.avg.speed=total distance/total time taken

=225/5=45km/h

4.b

5.d velocity

6.c.direction of velocity..

3.avg speed=10+10/8

=20/8m/s

avg.velocity =0m/s
