Two buses F and G are operated between cities I and J.
One day F and G started from I and J respectively towards J and I respectively.
After the two buses cross each other, the bus F takes 5 hours to reach city J and the bus G takes 3 hours 12 minutes to reach city I.
After how much time from the start did the buses F and G cross each other.

It doesn't say they started at the same time and assuming the buses travel at the same speed:
Bus F met Bus G 3.2 hrs after it started
Bus G met Bus F 5 hrs after it started
