Question

Hello is it possible to receive help on this question? I would like to understand the format needed to solve the question. Thank you!

Answer 1

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.
