Step-by-Step Solution
The engines close at km/h, so they draw level after h. Flying non-stop at 90 km/h, the pigeon covers km — no need to sum the back-and-forth legs.
Answer: A) 2 km
On parallel tracks two trains approach each other at 36 km/h and 54 km/h. When their engines are 2 km apart, a pigeon flying at 90 km/h starts shuttling between the engines until they are level. How far does the pigeon fly?
