Two trains each of having a speed of 30 km/h are headed at each other in opposite direction on the same track. A bird flies off one train to another with a constant speed of 60km/h when they are 60 km apart till before they crash. Find the distance covered by the bird and how many trips the bird can make from one train to the other before they crash.

Two trains, each having a speed of 30 km//h , are headed towards each other

Two trains, each with a speed of 50 kmph are headed towards each other on the same trake. A bird that can fly at the rate of 100kmph flies off one train when they are 100km apart and heads directly to the other train. On reaching the other train it flies back to the first train and so forth. (a) How many trips can the bird make from one train to the other before they crash ? (b) How is the total distance the bird travels ?

Two trains, each having a speed of 30 km/h, are headed at each other on the same track. A bird that can fly 60 km/h flies off the front of on train when they are 60km apart and heads directly to the other train. On reaching the train, the bird flies back to the first train. What is the total distance the bird travels before the train collide?

Two trains cross each other at speeds of 36 km//h and 54 km//h travelling in the opposite directions in 2 sec. What is the length of the second train (in km)?

Two trains are headed towaads each other on the same straight rrach, each vaving a speed of 30 km h^(-1) . A bird that can fly at 60 km h^(-1) flies off one train when they are 60 km apart and leads firectly form the otjer train, On reaching the other train, tg flies back to the first train and so on. (a) How many trips can the bird make from one trin to the other train befre they meet ? (b) What is the total distance the bird travels ?

Two trains, each travelling with a speed of 37.5kmh^(-1) are approaching each other on the same straingh track. A bird that can fly at 60 kmph flies off from one train when they are 90 km apart and heads directly for the other train. On reaching the other train, it flies back to the first and so on. total distance covered by the bird before trains collide is
