Question

a bird on the wall spots an approaching train,which is 720 km away and movimg at a speed 54km/hr.the vurd start fkying towards train , it flies back toward the wall, it continue do this till time traim cashes the wall.If bird can fly a speed 120km/hr, Fund the total distance covered by bird while it flying toward wall

Answer 1

train is approaching towards the wall so time taken by it to reach the wall is 720/54, where 15 m/s is 54 km/hr. now the time taken is 40/3 hours. now in 40/3 hours the bird will cover a distance at its own speed. therefore distance covered by speed is 40/3*120. therefore distance traveled by the bird is 1600 km. now since the bird flows to and fro distance traveled is equal. therefore towards the wall it covers 800 kilometers.

Hope this helps!

Answer 2

Answer:

800 km

Step-by-step explanation:

first write the distance =720

then speed =54

=720 /54

after dividing the sum will 40 /3

=15m/s=54 km /hr

=40/3*120

=1600

the bird have to move toward the wall so ,

1600 will be divided by 2

=800
