When the train starts, the taxi has been going for 70 minutes.
The taxi has then travelled 58 1/3 km
When the train starts it travels 60 kph faster than the taxi, so, how long does it take the train to catch up the 58 1/3 km at 60 kph = 58 1/3 minutes
in hours this is 0.97222222
So it overtakes at 9:58:20 am

What was the train doing at the taxi stand?
rt=d
rt=rt
50*x=110*(x-1 1/6)
=77/36=72/36 +5/36=2.13889 hours
The taxi travelled for 2 hours 8 minutes 20 seconds
7:50+2:8:20=9:58:20
The train travelled for 00:58:20 hours or 58 minutes 20 seconds
They met at 9:58:20 am
