Q. 24. Two trains, each having a speed of 30km/h, are headed at each other on the, same track. A bird flies off one train to another with a constant speed of 60kmv/h, when they are 60km apart till before they crash. Find the distance covered by the, bird and how many trips the bird can make from one train to other before they, crash?, , Answer : Given, speed of each train = 30 km/h and, , Distance between them = 60km, , As they are moving in opposite direction and same speed,, , So they will crash at middle of the distance between them, i.e. 30km from each train., Time taken to travel 30 km by each train = == th, , Speed of the bird = 60 km and time = 1h, , So distance traveled by bird in 1h = speed x time, =60x1, , =60km, , As trains will come closer to each other, bird can make any number of trips because, distance between trains will approach to 0., , So the time taken by bird will also tends to 0. Therefore, bird can make infinite number, of trips.
