Let's make a diagram to visualize the problem.

Let's find the distance covered by car A using the formula d = v*t.

$d_A=v\cdot t=40\cdot(mi)/(h)\cdot5h=200mi$

Car A covered 200 miles.

Subtract to obtain the distance covered by car B.

Then, we use the formula v = d/t to find the speed of car B.

$\begin{gathered} v_B=(d_B)/(t)=(175mi)/(5h) \\ v_B=35\text{mph} \end{gathered}$
