0 votes

Two trains are on same track and they are coming toward each other. The speed of first train is 50 KMs/h and the speed of second train is 70 KMs/h. A bee starts flying between the trains when the distance between two trains is 100 KMs. The bee first flies from first train to second train. Once it reaches the second train, it immediately flies back to the second train … and so on until trains collide. The speed of bee is 40 KMs/h. Calculate the total distance traveled by the bee?

The Bee cant make it as:
1. Both Trains have higher speed than the bee
2. Trains collide after 100KMs/(50 KMs/h+70KMs/h)=50 mins, the bee travels only 40*50/60=33.3 KMs by that time

Accidentally, two trains are running in the opposite direction and enter a tunnel that is 200 kms long. A supersonic bird that has fled the lab and taken shelter in the tunnel starts flying from one train towards the other at a speed of 1000 kmph. As soon as it reaches the second train, he starts flying back to avoid collision and meets the first train again at the other end. The bird keeps flying to and fro till the trains collide with each other.

What is the total distance that the supersonic bird has traveled till the trains collided?
