A bus takes 30 minutes to travel a distance of 25 kilometers. The speed of the bus in km/h is :

• 55 km/h

• 50 km/h

• 5 km/h

• 75 km/min

SI unit of time is:

• minute

• hour

• second

• mili seconds

The above distance time graph shows

• An object moving with uniform motion

• An object moving with non uniform motion

• An object at rest

The given graph represents

• Speed of A < Speed of B

• Speed of B < Speed of A

• Speed of A = Speed of B

• body is at rest
