A fly is flying between two trains, each travelling towards
each other on the same track at 60 km/h. The fly reaches one
engine, reverses itself immediately, and flies back to the
other engine, repeating the process each time.
The fly is flying at 90 km/h. If the fly flies 180 km before
the trains meet, how far apart were the trains initially?

Answer Posted / guest
Initially, the trains were 240 km apart.
The fly is flying at the speed of 90 km/h and covers 180 km.
Hence, the fly flies for 2 hours after trains started.
It's obvious that trains met 2 hours after they started
travelling towards each other. Also, trains were travelling
at the speed of 60 km/h. So, each train traveled 120 km
before they met.
Hence, the trains were 240 km apart initially.
