As given by the question

there are given that the one car travels 5 mi/h faster than other cars.

Now,

Let one car travel at x mph, the other car travels


x+5

Then,

Their combined speed is:


2x+5

Now,

distance is 230

So,


\begin{gathered} \text{time}=(230)/(2x+5)=5 \\ (230)/(2x+5)=2 \\ 230=2(2x+5) \\ 230=4x+10 \\ 4x=230-10 \\ 4x=220 \\ x=55 \end{gathered}

Then,

The other car travels at:


55+5=60

So, the first car travel is 55mi/h and another car is 60 mi/h.

Hence, the correct option is B.
