two trains each havin a speed of 80km/hr are headed towards each other on the same straight track ..a bird that can fly 60km/hr flies off the front of one train when they are 60 kms apart on reaching the other train heads for the first one again and so on ...what is the total distance travelled by the bird???

Dear shivanshi

total time taken by train to meat = 60/(80+80)

                                                =3/8 hr

so in this tome interval distance moved by fly is = 60 * 3/8 =22.5 km
