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 speed and average velocity of Usha.

The distance betweenn two place A and B is 180 km by road adn 120 km by air. An aeroplane takes 20 min to go from A to B whereas a deluxe bus strarting at A takes 5h to reach B. Find the average speed and average velocity by both means of transport) (Ignore the vertical ascent of aeroplane)

A Physics teacher is explaining the difference between average speed and average velocity to her students. Where average velocity = ("displacement")/("time taken") , "average speed" = ("actual distance travelled")/("time taken") She emphasises that average speed is more relevant than average velocity, because displacement from one place to other is only theoretical, being the shortest distance between two places. Average speed is the real entity that matters, taking into account the actual time taken to travel the actual distance between the two stations. Read the above passage and answer the following question : (i) Do you agree with the statement of Physics teacher ? (ii) The shortest distance between Ambala to Delhi is 200 km . A train takes 4 hrs and covers a distance of 210 km in going from Ambala to Delhi via Karnal. Another train takes 5 hrs and covers 250 km distance in going from Ambala to Delhi via Saharanpur. What is the average speed of these two trains? What would be the average velocity of a train that takes 2.5 hrs to cover 200 km distance ? (iii) What values do you learn from this discussion ?
