Question

The following table gives the data about motion of a car time 11.00 11.30 in 12.00 12.30 1.00 distance 0 30 30 6500 find the speed of a car between 12.00 hours in 12.30 hour. what is the average speed?

Answer 1

First right the table properly

Time. Distance.

11:00. 0m ( that means the object is in rest.)

11:30. Om. ( the object is still at rest.)

12:00. 30m (the object moved 30m between 11:30 to 12:30

12:30. 30m ( but here the object is still at a distance of 30m that means the object has moved 0m between 12:00 to 12:30)

1:00. 6500m ( the object has moved 6500-30=6470m between 12:30 to 1:00)

So the answer is very simple

We know

Time (3600s)

Distance ( 0m )

And we need speed

We use the formulae for speed

D/t=v

Om/3600s= 0m/s is the speed between 12:00 to 12:30.
