\( A=\left[\begin{array}{lll}390 & 410 & 430 \\ 590 & 600 & 650 \\ 510 & 470 & 460\end{array}\right] \) (a) Find a matrix \( B \) whose entries are the times (in hours) spent flying each day. Make sure the product \( A B \) is defined and its entries are the distances (in kilometers) each pilot flew overall. \( B=\left[\begin{array}{l}2 \\ 3 \\ 4\end{array}\right] \) \( A B=\square \) (b) Calculate the product \( A B \). \[ \]
