Remember: ---> ------> eqn 1
--------------> eqn 2

Note: before T[2] started travelling, T[1] has been running for 1 hour and the total distance travelled: via eqn 2,
-------> eqn3
Now, remember eqn 1: we take the total distance travelled minus eqn 3 (50m). Then we add the speed for both in achieving the distance apart:

-----------> it took for and when 350 miles apart.
For -----> + (eqn3) = total time travelling.
Thank you,
