here you go

Step-by-step explanation:

So 15 hours after the second train leaves, they will be at the same distance. This is at 8AM since the second train leaves at 5PM.

When n=1 , we have

$\dfrac n{2n+1}=\dfrac1{2\cdot1+1}=\dfrac13$

When n=2 , we have

$\dfrac n{2n+1}=\dfrac2{2\cdot2+1}=\dfrac25$

and so on. The series is then

$\displaystyle\sum_{n=1}^6\frac n{2n+1}=\frac13+\frac25+\frac37+\frac49+\frac5{11}+\frac6{13}$
