To solve the problem, we need to find Usha's average speed and average velocity while swimming in a 90 m long pool. ### Step 1: Understand the given information - Length of the pool = 90 m - Total distance covered by Usha = 180 m (going from one end to the other and back) - Time taken = 1 minute = 60 seconds ### Step 2: Calculate the average speed ...

A and B are two fixed spots in a river in which water has a steady sped v_(w) . A person who can swim with a speed v relative to water swims from A to B and back to A alomg shortest path. If the water is still, the person will take a time 30 minute in swimming from A to B and back to A along the shortes path. But we know that water is acually not still. The person also knows the technique of just flowing with water without exerting his own effort. Using this technique, i.e., just being carried with water, he takes a time 20 minute in moving from A to B . As shown, X and Y are two places directly oppsite to each other on oppsite banks. Assuming that width of the river is the same as the distance A and B , answer these questions. (assume v gt v_(w) ) Choose the correct option(s) :

A bird files between two trains approaching each other with constant speed of 10 m/s each. Trains are initially 1 km apart. The bird starts from the first train and as it arrives just in front of the other train it turns and continues the same process. The average velocity of the bird till it is sandwiched between the trains is:
