SOLUTION: Two trains each having a speed of 43kph are headed onto each other on the same straight track. a bird that can fly at 53 kph flies off the front of one train when they are 162.0 km

Question 986462: Two trains each having a speed of 43kph are headed onto each other on the same straight track. a bird that can fly at 53 kph flies off the front of one train when they are 162.0 km apart, and heads directly for the other train . on reaching other train , it flies back to the first train , and so forth. how many trips can a bird make before the trains collide? what is the total distance the bird travels?

The two trains each have a speed of 43 kph. Therefore they are approaching each other at 86 kph. Since they are 162 km apart when the bird starts, they will collide in

hours. The bird, at 53 kph, will fly

km, presuming that that this particular bird is capable of reversing direction instantaneously.

The other part of the problem is another story. Write back and we'll talk.
