Question

Questions,
1 Two trains AandB 60km apart are approaching
each other with speed 30km/hr. A bird flies
to and fro B/w AandB with a speed 60km/hr
until they collide.
Find the distance covered & Displacement of the
Bird?​

Answer 1

Answer:60 kilometer.

Given:

Speed of train: 30 km/hr

Speed of bird : 60 km/hr

Distance between two train : to be found?

Solution:

As given that both the train are running on same speed which is 30 km/hr so both the train will expected to met or collide at 30 km and the time taken in this is :

    t =distance travelled/speed of train  

      =30 km/30 kmph

      =1.00 hr

so, the birds that flying 60 km/hr will travel would be before the train colloid is :

    Distance= time taken × speed of bird

      = 1 × 60 = 60 km
