From the position-time graph given find the average speed

An express train takes 1 hour less than a passenger train to travel 132 km between Mysore and Bangalore (without taking into consideration the time they stop at intermediate stations). If the average speed of the express train is 11 km/hr more than that of the passenger train, find the average speed of the two trains.

Draw velocity-time graph for a body moving with uniform velocity. Hence show that the area under the velocity-time graph gives the distance travelled by the body in a given time interval.

Usha swims in a 90 m long pool. She covers 180 m in one minute by swimming from one end to the other and back along the same length path. Find the average speed and average velocity of Usha.

If a body cover a distance x with speed v_1 and then it covers another distance x with speed v_2 , find the average speed for the whole journey.
